Mycosis Fungoides: Tumour d'emblee.

Mycosis Fungoides is a Cutaneous T-cell lymphoma characterized by infiltration of skin with patches, plaques, and nodules composed of T-lymphocytes. It is the most common type of Cutaneous T-Cell Lymphoma and accounts for almost 50% of all primary cutaneous lymphoma. Tumour d’ emblee is the term used for the patient presenting with skin tumors not preceded by patches or plaques. We report a rare case of mycosis fungoides d’ emblee variant with tumors of only 3 months duration without any preceding skin lesions.

Lupus pernio without systemic involvement

Sarcoidosis is a multisystem, granulomatous disease of unknown etiology that can affect the pulmonary, reticulo-endothelial, skin, gastrointestinal, cardiac, musculo – skeletal, endocrine or central nervous system. Exclusive cutaneous involvement is very rare in sarcoidosis. Lupus pernio is a variant of cutaneous sarcoidosis presenting with erythematous to violaceous nodules and plaques located symmetrically over the nose, cheeks, ears and digits. We present a case of lupus pernio which showed rapid improvement with topical steroids and has yet not developed any systemic involvement even after 6 years of regular follow up.

Ofuji's disease in an immunocompetent patient successfully treated with dapsone

Eosinophilic pustular folliculitis or Ofujis disease is a non-infectious eosinophilic infiltration of hair follicles, which usually presents with itchy papules and pustules in a circinate configuration. We report this case of an immunocompetent patient with erythematous papules and plaques without macropustules diagnosed as eosinophilic pustular folliculitis—a rarely reported entity outside Japan. He was successfully treated with oral dapsone.

Multifocal Cutaneous Tuberculosis in Immunocompetent Individual.

Most common form of cutaneous tuberculosis (TB) is lupus vulgaris, which usually occurs in previously sensitized individuals who have a high degree of tuberculin sensitivity. Various forms including plaque, ulcerative, hypertrophic, vegetative, papular, and nodular forms have been described. We are reporting a case of a young female, who presented with 6 well defined erythematous scaly plaques involving both arms and a puckered scar on right forearm and right breast. Clinically, it was looking like lupus vulgaris with cold abscess, few lesions mimicking scrofuloderma, but skin biopsy from both the types of lesions revealed lupus vulgaris. Patient improved with Anti Tuberculous Therapy and surgical drainage of underlying cold abscess.

Christ-siemens-touraine syndrome: case report of 2 brothers.

Ectodermal dysplasia is a rare disorder. Christ-Siemens-Touraine syndrome (Hypohidrotic Ectodermal dysplasia (HED)) is a diffuse, non-progressive disease present at birth and involves at least two tissues of ectodermal origin. It is caused by mutation in gene ectodysplasin (EDA, EDA1) located at Xq12-13. Main clinical feature of HED is sparse or absent eccrine gland as well as hypotrichosis, nail, and teeth abnormality with characteristic faces. The absence or diminished activity of sweat gland results in patients having more chances of developing hyperthermia and with intolerance to warm environment. Most do well with simple measures such as wet clothes, air conditioning, wet bands etc. We present cases of two brothers, born of non-consanguineous marriage, who presented to us with complaints of heat intolerance and abnormal facial features.

Cutaneous angiosarcoma of head and neck

Cutaneous angiosarcoma is a rare aggressive tumor of capillary and lymphatic endothelial cell origin. Cutaneous angiosarcoma of the head and neck regions seems to be a distinctive neoplasm with characteristic clinicopathologic features that differ from angiosarcoma in other anatomic locations. Angiosarcoma, regardless of their setting, has a bad prognosis. We presented here a case of 80 years old male, with multiple nontender grouped purple to red hemorrhagic vesicular and bullous lesions over left lower cheek and upper neck area, with bilateral cervical lymph nodes since 1 month. Computed tomography thorax showed nodular opacities in the right upper and midzones. Excisional biopsy showed characterstic “dissection of collagen” with mild nuclear atypia. Immunohistochemistry showed tumor cell positive for CD-31 and Fli-1. Patient died within 1 month of presentation.

In Vivo Anti-psoriatic Activity, Biodistribution, Sub-acute and Sub-chronic Toxicity Studies of Orally Administered Methotrexate Loaded Chitin Nanogel in Comparison with Methotrexate Tablet

The anti-psoriatic efficacy of orally administered methotrexate loaded chitin nanogel (MCNG) was evaluated (two doses- 2.715 mg/kg and 5.143 mg/kg) and compared against orally administered methotrexate tablet MTX (5.143 mg/kg). MCNG at both dose levels of 2.715 mg/kg and 5.143 mg/kg exhibited significant anti-psoriatic activity which is very much comparable with MTX, caused normalization of histological features and inflammatory score associated with induced psoriasis. Biodistribution studies revealed the presence of drug in serum and in vital organs at all the three cases with highest amount in MCNG at 5.143 mg/kg dose, followed by MTX tablet and are lowest in MCNG at 2.715 mg/kg dose. MCNG at the highest dose of 5.143 mg/kg caused liver, lung and kidney toxicities on sub acute toxicity studies and MTX tablet was found to be toxic on liver and lung on sub chronic toxicity studies. MCNG 2.715 mg/kg was found to be safe on both sub acute and sub chronic administrations, suggesting that it can provide sufficient serum and tissue level of methotrexate necessary to clear psoriatic lesions, without inducing systemic toxicity and expected to be a better alternative for orally administered conventional methotrexate tablet for patients who need systemic medications for psoriasis.

Mycobacterium chelonae infection complicating traumatic and surgical wounds: A case series

Mycobacterium chelonae is a rapidly growing non-tuberculous mycobacterium. The skin and soft tissue infections due to this organism are steadily on the rise and need to be delineated specifically as most of these are not responsive to routine antituberculosis treatment. Here, we report 3 different presentations caused by Mycobacterium chelonae in traumatic and surgical wounds. Mycobacterium chelonae can complicate surgical or traumatic wounds.This infection may also present as injection site abscesses. Diabetics on insulin injections are especially at risk. A high index of suspicion is necessary in long standing culture negative lesions for clinching the diagnosis. PCR can be helpful in confirming the diagnosis.

Study of clinical profile of herpes zoster in human immunodeficiency virus positive and negative patients at a rural-based tertiary care center, Gujarat

Background: Herpes zoster usually presents with typically grouped vesicles on erythematous base involving single dermatome with self-limiting nature in immunocompetent individuals while it may present in extensive form involving multiple dermatomes involvement or disseminated form in immunocompromised, especially in human immunodeficiency virus (HIV). Aims and Objectives: The aim of this study was to study the prevalence of HIV in patients of herpes zoster, to compare the clinical presentation of herpes zoster in HIV-infected and noninfected patient. Materials and Methods: The study was carried out in the Department of Dermatology in a Teaching Institute of Gujarat, from June 2008 to May 2014 after ethical clearance. The study population included all the patients with a clinical diagnosis of herpes zoster. All the patients were investigated for HIV infection after written consent. Results: Out of total 688 patients of herpes zoster, 35 (5.1%) were HIV-positive, 26 (74.3%) were males and 9 (25.7%) were females. Among HIV-positive patients, 29 (82.85%) patients had localized dermatomal involvement, 4 (11.42%) patients had multiple dermatomal involvement, and only 2 (5.71%) had disseminated zoster while among HIV-negative, 636 (97.40%) had localized dermatomal involvement, 14 (2.14%) patients had multiple dermatomal involvement, and 3 (0.45%) had disseminated zoster. Cervical dermatome was most commonly involved dermatome in patients of HIV. Conclusion: Disseminated and multiple dermatomal involvement was more commonly involved among HIV-positive patients when compared to HIV-negative patients.
