Allergic contact dermatitis mimicking angioedema due to paraphenylendiamine hypersensitivity: a case report

Active sensitization to paraphenylendiamine (PPD) and related compounds from temporary black henna tattoos has become an epidemic in the recent years. Hair dyes also include PPD like black henna tatoos which cause allergic contact dermatitis. Skin lesions of allergic contact dermatitis from PPD are mostly seen as an exudative erythema, an erythema multiforme-like eruption or a bullous contact dermatitis. We, herein, report a 27 year-old woman with an angioedema-like reaction occurring after the first exposure to hair dye who was unaware of being previously sensitized to PPD from black henna tattoo.

Ross syndrome: Unilateral hyperhidrosis, Adie's tonic pupils and diffuse areflexia.

Ross syndrome is a rare disorder first described in 1958 with partial autonomic dysfunction. It has three basic components including unilateral or bilateral segmental anhidrosis, Adies tonic pupils and areflexia or hyporeflexia of deep tendon reflexes. The most disturbing symptom in the patients is segmental compensatory hyperhidrosis and often the hypohidrosis or anhidrosis is not even noticed. While the pathogenesis of Ross syndrome is unclear, degenerative changes or damage to the peripheral autonomic nerve system or dorsal root ganglia have been suggested as possible causes. About 50 cases have been reported, usually by neurologists and ophthalmologists, and less often by dermatologists. We present a 26‐year‐old patient who displayed the classic triad of this syndrome, emphasizing that the presenting complaint may be hyperhidrosis and that multidisciplinary evaluation in neurology and ophthalmology is essential.

Variable clinical presentations of Classic Kaposi Sarcoma in Turkish patients

BACKGROUND Kaposi sarcoma (KS) is a vascular neoplasm with multicentric cutanenous and extracutaneous involvements, which was first described by Moriz Kaposi in 1872. Since then, different epidemiological clinical and histopathological variants of this neoplasm have been identified. Classic Kaposi sarcoma (CKS) is one of four main clinico-epidemiologiologic variants. characteristics of the disease. MATERIALS AND METHODS Four Turkish inpatients with CKS were evaluated in the study. All medical history and clinical data were noted. A screening immunodeficiency workup were performed for all patients. HHV-8 immunofluorescence testing on the specimens and ELISA test for human immunodeficiency virus (HIV 1 and 2) were performed. Pulmonary X ray graphies and computurized tomography (CT) scan were applied. Stage of the tumor was determined, in each case, according to the classification system proposed by Brambilla et al in 2003. RESULTS All patients are positive for HHV-8. They were all immunocompetent and negative for HIV1 and HIV2. The first patient was unusual for morphological presentation of several verrucoid lesions that was evaluated as verrucoid KS. He was considered stage IB CKS. The patient 2 was a young man and the course of KS seemed unexpectedly aggressive for CKS. His clinical appearence seemed us to be a patient with AIDSassociated KS. The patient was evaluated as stage IVB CKS. Our third patient had also prominent lymphedema associated with bluish discoloration on the toes and fingers, suggesting a diagnosis of peripheral vascular disorder. He was diagnosed as stage IIIB CKS. The fourth case was interesting for very extensive lesions involving big sized plaques and also the existence of mucosal lesion. The patient was diagnosed as stage IVB CKS. CONCLUSIONS It seems that the reports of exceptional cases of KS are accumulating. Data from various cases should be collected and perhaps, novel clinical classifications should be considered.

Linear atrophoderma of Moulin on the neck.

BACKGROUND Linear atrophoderma is a rare disease, first described by Moulin in 1992 in 5 patients. It is an acquired unilateral hyperpigmented, depressed band-like areas following the lines of Blaschko. It affects children or adolescents of both genders involving the trunk or the limbs. It is considered to be a rare cutaneous form of mosaicism. MAIN OBSERVATION A 39-year-old woman with a 22 years history of unilateral slightly depressed hyperpigmented lesion on her neck was admitted to us. The skin texture was normal and there were no signs of induration or sclerosis. The histopathological examination revealed a normal epidermis outlined by a hyperpigmented basal layer. In the papillary dermis proliferation of superficial vessels with mild lymphocytic infiltrate and melanin-laden macrophages were present. The collagen fibres and elastic fibres were normal. The clinical and histopathological features confirmed the diagnosis of linear atrophoderma of moulin. We discussed the case according to the other cases reported in the literature. CONCLUSIONS Approximately 28 cases of linear atrophoderma have been reported in literature. The present case has the charecteristic clinical and histopathological features of linear atrophoderma as defined by Moulin, but the localization of the lesion is unusual.

Lupus erythematosus and lichen planus overlap syndrome:a case report with a rapid response to topical corticosteroid therapy

Lupus erythematosus (LE) and lichen planus (LP) may occur as an overlap syndrome. We report the clinical characteristics of a young man with lesions diagnosed as LE and LP by histopathological and direct immunoflurosence examinations. We achieved remarkable clinical response from the treatment with topical corticosteroids and no recurrence was seen in a 6 months of follow up time. We found this case interesting because of the rapid improvement with corticosteroid and discussed if there is a real overlap or a coexistence according to the literature.

Is it a sarcoidal foreign-body granuloma or a cutaneous sarcoidosis on a permanent eyebrow make-up?

Permanent make-up is a kind of cosmetic tattoo in which the colorants (pigments) are deposited in dermis after piercing the skin by tiny solid needles. It may cause some adverse effects such as local inflammation, infection, and allergic reactions on the skin and even systemic adverse effects such as sarcoidal reactions. Here the case of a 34-year-old woman who has some yellowish hard shiny papules on her eyebrows after having a permanent make-up is described. The histopathological examinations of the papules are diagnosed as sarcoidal foreign-body reactions. All the laboratory investigations were in normal limits except a mild elevation in angiotensin converting enzyme or ACE level. The lesions mostly improved after topical corticosteroid treatment. Sarcoidal foreign-body reaction due to permanent make-up is discussed with this presentation.

A rare complication of follicular hair unit extraction: Kaposi’s varicelliform eruption

Follicular hair unit extraction (FUE) is becoming a popular type of hair transplantation recently. Kaposi’s varicelliform eruption (KVE) is an uncommon skin emergency due to cutaneous dissemination of several types of viruses, most notably herpes virus, over the lesions of preexisting skin disorders. A 34-year-old man visited our dermatology outpatient clinic with a blistering, itchy and tender eruption on his head and body. He had undergone follicular FUE for androgenic alopecia 12 days previously, and 5 days after the procedure, umbilicated and/or hemorrhagic vesiculopustules appeared firstly on the occipital scalp skin where the hair units were taken. The lesions had rapidly spread over the upper chest and back. After the operation, he had taken oral methylprednisolone, amoxicillin clavulanate and had used fusidic acid ointment without any benefit. Bacterial culture of the pustules yielded no microorganism, while Tzanck smear from the vesicles revealed multinuclear giant cell groups. Based on a diagnosis of KVE, we treated the patient with oral valacyclovir hydrochloride 1000 mg 3 times a day for 14 days. Symptoms cleared rapidly, pustules and vesicles dried in a few days, and re-epithelialization of the eroded areas started at the end of the first week. The reported complications of FUE include necrosis of the donor site, postoperative hyperesthesia, recipient area folliculitis, keloids, bleeding, infection and pyogenic granuloma. Up to this date there are only three reports of KVE developing just after dermatological surgery, including dermabrasion, laser resurfacing, and skin grafting. According to our knowledge, this is the first case of KVE occurring after the FUE procedure. We think that the traumatic effects and skin barrier disruption due to operation and immune alteration due to postsurgical steroid treatment might have precipitated the activation and dissemination of latent herpesvirus infection.

Prevalence of Congenital Cutaneous Anomalies in 1000 Newborns and a Review of the Literature

OBJECTIVE There are limited reports studying on congenital cutaneous anomalies in newborns, particularly in Turkey. Some of congenital cutaneous anomalies serve as an important clue for accompanying syndromes or other medical conditions. This study aimed to determine the prevalence of congenital cutaneous anomalies in newborns and to discuss their clinical significance with a brief review of literature. STUDY DESIGN A total of 1,000 newborns were examined by a dermatologist in a hospital-based, cross-sectional, prospective study between October 2011 and April 2012. RESULTS We observed 11 different congenital cutaneous anomalies in 48 newborns of 1,000 (4.8%). The most commonly seen anomalies were sacral dimple, accessory nipple, acrochordon, hypospadias, open spinal dysraphism, and accessory tragus. None of the newborns with cutaneous anomalies had any association. CONCLUSIONS Although congenital cutaneous anomalies are rare in newborns, clinicians should be aware of them as they may be in association with syndromes and other medical conditions. It is also important to give appropriately provided information to avoid parents concerns.

Variable clinical presentations of secondary delusional infestation: an experience of six cases from a psychodermatology clinic.

Objective: Delusional Infestation (DI) is a relatively rare condition with a fixed belief of being infested with living organisms, despite a lack of medical evidence of such infestation. Although it seems to be a psychiatric disease, patients commonly are admitted to dermatology clinics because of skin findings. Psychiatrists can underestimate its prevalance, whereas dermatologists can miss the diagnosis. It should be managed as a psychodermato-logical disease. Our aim in the study was to evaluate six patients with different clinical presentations of DI and to emphasize some clinical features. Method: All patients were internalized in the psychodermatology clinic for this study. Medical history and clinical data from dermatologic and psychiatric examinations were noted; Mini International Neuropsychiatric Interview (MINI-Plus) and laboratory investigations including blood and urine analyses, microscopic analysis of so-called pathogens, and skin biopsy if needed, were performed. The diagnosis was made based on detailed history, dermatologic and psychiatric examinations, and laboratory investigations. Results: All patients had symptoms of itching, burning, or crawling sensations dermatologically and thus were admitted to dermatology clinic. They were all considered secondary DI to another medical condition or to psychiatric illness. Vitamin B12 deficiency, diabetes, and hypothyroidism were the underlying medical conditions. Related psychiatric illnesses were trichotillomania and schizoaffective disorder, schizophrenia, shared pychotic disorder, and brief psychotic disorder. Two patients had delusions of inanimate materials; four patients had partial and complete remissions; and two patients have dropped out. Conclusion: Each patient had different clinical characteristics creating diagnostic challenges. All complaints were related to the infestation of the skin. The presence of different psychiatric comorbidities is remarkable. It seems that both psychiatrists and dermatologists can face diagnostic and therapeutic challenges of this complex disease in clinical settings, particularly if there are unusual clinical features of DI. Therefore, both psychiatrists and dermatologists should be well aware of DI.

A giant benign clear cell hidradenoma on the anterior trunk.

Clear cell hidradenoma (CCH) is an uncommon variant of benign cutaneous adnexal tumors. These tumors are clinically asymptomatic, solitary dermal nodules. They occur most frequently on the scalp, face abdomen and extremities. Growth is slow and malignant change is rare. 45-year-old woman presented with a nodule which had begun 4 years ago as a small nodular asymptomatic lesion and had a central ulceration and a minimal hemorrhagic discharge on her anterior abdomen wall. On dermatologic examination there was a 6.5×5×4 cm non-tender, soft reddish purple nodule, with lobular appearance and ulceration. In the laboratory investigations, all hematologic and biochemical tests were normal. A computed tomography (CT) scan demonstrated a cystic tumor with lobulated contour with contrast enhancement. The lesion was excised totally. In histopathological examination, the tumor was composed of biphasic smaller dark polygonal cells and larger clear cells and coarse nuclear chromatine. There were duct like structures. Immunohistochemical investigation was done for the suspicion of malignancy. Cytoplasm of clear cells and of duct like structures showed PAS-positive and d-PAS resistant staining. There was a positive reaction to epithelial membrane antigen and carcinoembryonic antigen. The mitotic index in Ki 67 examination was low. All these findings confirmed the diagnosis of benign CCH.
