Cutaneous tuberculosis in Indian children: the importance of screening for involvement of internal organs

Aims and objectives  Resurgence of skin tuberculosis especially with drug‐resistant strains has been well documented in recent years, but this problem has not received much attention in the paediatric age group. Hence, we carried out the present study to analyse the clinical and therapeutic aspects of cutaneous tuberculosis in children.

Cutaneous tuberculosis in children and adolescents: a clinicohistological study.

Background and objectives  Resurgence of tuberculosis (TB) in the era of human immunodeficiency virus (HIV) has rejuvenated the interest in this global health problem. Cutaneous TB, an important extra‐pulmonary form in children, is commonly seen in our dermatological practice. As detection of acid‐fast bacillus (AFB) on smear or culture is not always positive, histopathology is necessary to help in diagnosing and classifying the variants of skin TB. The current study was conducted to analyse the clinicopathological characteristics of cutaneous TB in children and adolescents.

An observational analysis of erythromelanosis follicularis faciei et colli

Erythromelanosis follicularis faciei et colli (EFFC) is characterized by well‐demarcated erythema, hyperpigmentation, and follicular papules. Since the orginal description, < 50 patients have been reported in the literature. Five cases of EFFC have been seen in our outpatient department in the past 5 years. All patients except one presented with the classic triad of erythema, brown pigmentation and follicular papules on the face and keratosis pilaris lesions on the trunk. In all cases, there was no family history for related disorders or history of atopy. Histopathological examination in all cases was consistent with the diagnosis of EFFC. Age at presentation ranged from 11 to 19 years, and the male female ratio was 4 : 1. Patients had the classic lesions of keratosis pilaris on the face (5/5), trunk (2/5) and legs (4/5). All patients except one had a background of erythema. One patient (patient 2) had itching and a history of photosensitivity. Of the patients who were on treatment (4/5), complete clinical regression was seen in one patient. To our knowledge, this is the first case series of EFFC from India, and we believe that EFFC is a common but infrequently reported condition.

Malignant peripheral nerve sheath tumor of the breast: case report

BackgroundMalignant peripheral nerve sheath tumor is a rare soft tissue sarcoma of ectomesenchymal origin. It is the malignant counterpart of benign soft tissue tumors like neurofibromas and schwannomas and may often follow them. Common sites include deeper soft tissues, usually in the proximity of a nerve trunk. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer.Case presentationA 38-year-old female presented with complaints of painless, hard breast lump for three months which was clinically suspected to be a ductal carcinoma with inconclusive fine needle aspiration cytology. Histopathology revealed a malignant spindle cell tumor which was confirmed to be malignant peripheral nerve sheath tumor on the basis of immunopositivity for vimentin, neurone specific enolase and S-100.ConclusionTo the best of our knowledge only six such case reports have been published in literature. The differential diagnosis of malignant peripheral nerve sheath tumor should be considered by the clinician as well as the pathologists in the work-up of a breast neoplasm as treatment and prognosis of this rare malignancy is different.

Primitive neuroectodermal tumor of prostate.

Primitive neuroectodermal tumors (PNETs) are malignant proliferations of small, undifferentiated neuroectodermal cells occurring mainly in children and share the same reciprocal translocation between chromosomes 11 and 22 and the same patterns of biochemical and oncogene expression as osseus and extraosseus Ewings sarcoma. Some PNETs occur in the brain, while others (the peripheral PNETs) occur in sites outside the brain, such as in the extremities, pelvis and the chest wall. They mostly originate in the chest, pelvis and retroperitoneum; in rare cases, occurrence in the head and neck area has also been seen. We present a rare case of primitive neuroectodermal tumor arising in the prostate gland in a 25-year-old male. To the best of our knowledge, this is the first documentation of a primary peripheral primitive neuroectodermal tumor in the prostate gland of any patient from India and rarely reported in English literature.

Demodex-associated dermatologic conditions--A coincidence or an etiological correlate. Review with a report of a rare case of sebaceous adenoma.

Demodex folliculorum is a saprophytic mite of the human pilosebaceous unit with a prelidiction for facial skin and eyelashes. Infestation occurs frequently without symptoms; however, suppurative or granulomatous inflammation may be seen with high mite density. Skin lesions, such as rosacea, pityriasis, and blepharitis, have been attributed to Demodex; however, its role in sebaceous adenoma (SA) has not been reported in extensively searched medical literature. We report this rare case and review the skin lesions associated with Demodex folliculorum.

Morphological findings in bone marrow biopsy and aspirate smears of visceral Kala Azar: a review.

CONTEXT Visceral leishmaniasis (VL) is endemic in India and may simulate and cause many hematological disorders like pancytopenia, myelofibrosis, myelodysplasia and hemophagocytosis. AIMS The study aims to investigate the hematological manifestation of Visceral Leishmaniasis and associated changes that may be observed in bone marrow aspirate smears and biopsy which may warn a pathologist of possible infections. SETTINGS AND DESIGN This is a retrospective study of 18 VL cases on B (b) one marrow aspirate and biopsy in the department of Pathology in a tertiary care teaching hospital in New Delhi. METHODS AND MATERIAL Giemsa stained slides of bone marrow aspirates and hematoxylin and Eosin stained biopsy slides were reviewed in detail by two competent pathologists. All the findings were tabulated and discussed and comparisons made with the previous similar studies. RESULTS Hyper cellular marrow, increased lymphocytes and plasma cells, marrow granulomas, hemophagocytosis, myelofibrosis, myelodysplasia and gelatinous transformation of the marrow were notable features the presence of which together or individually should caution a pathologist to search for Leishman Donovan (LD) bodies in patients especially in a non-endemic zone in a tropical country.

Clinico-pathological profile of 12 cases of chorangiosis

Chorangiosis is one of the vascular lesions that involvs terminal chorionic villi. It is commonly associated with various feto-maternal conditions like pre-eclampsia, diabetes etc. However, the clinical significance of this pathological finding has not been studied extensively. The aim of this study was to identify the various conditions associated with chorangiosis and to determine its clinical significance. A retrospective study to identify the cases of placentas diagnosed with chorangiosis was carried out and the clinical and morphological details of these cases were reviewed. Immunostaining for CD34 and muscle-specific actin was also performed to confirm chorangiosis and to exclude chorangiomatosis.A total of 12 cases of chorangiosis were retrieved, most of them were of term gestation. Five of these 12 cases were associated with various maternal conditions including syphilis (2 cases) and single cases of pre-eclampsia, diabetes and jaundice. One case in each had abruptio placenta and non-immune hydrops. Of these 12 cases, seven were stillborn. Microscopically, all 12 cases showed extensive chorangiosis involving terminal villi. In addition, two cases showed focal infarction and one had extensive calcification. Immunostaining for CD34 confirmed increased number of capillaries while muscle-specific actin was negative, excluding chorangiomatosis.The clinico-pathological profile presented in this study suggests that chorangiosis has characteristic pathological features for its recognition and needs to be differentiated from similar conditions like chorangioma and chorangiomatosis. Also, chorangiosis has potential clinical significance and should be mentioned in the pathology report and the patient should be investigated for associated conditions like syphilis, pre-eclampsia, diabetes etc.

Malignant mixed Mullerian tumor of broad ligament with synchronous ovarian and endometrial carcinoma: A rare association

Extragenital malignant mixed Mullerian tumor (MMMT) is a rare tumor in females, and it is even more rarely encountered among the multiple genital malignancies. There are some reports of extragenital MMMTs associated with synchronous or metachronous gynecologic tumors of Mullerian duct origin. We recently encountered an MMMT of broad ligament which is associated with papillary serous cystadenocarcinoma of the ovary and endometrioid adenocarcinoma arising in atypical polypoid adenomyoma endometrium in a 76-year-old woman. This case is presented for its rarity and unique presentation. To our knowledge, ours is the first reported case of this unique combination of multiple synchronous genital malignancies.

Cushing Syndrome in an Infant Due to Cortisol Secreting Adrenal Pheochromocytoma: A Rare Association

ABSTRACT Adrenocortical tumors are the most common cause of endogenous Cushing syndrome in infancy and early childhood. Cushing syndrome resulting from ectopic adrenocorticotrophic hormone (ACTH) producing tumor has been infrequently reported in adults. Cortisol secreting pheochromocytoma is rarely reported in literature. We report an eleven month old child presenting to us as Cushing syndrome with hypertension due to left adrenal tumor. He was treated with antihypertensives and left adrenalectomy was done under perioperative glucocorticoid coverage. Diagnosis of pheochromocytoma was made only after histopathology. Despite the rare association of Cushing syndrome and pheochromocytoma, preoperative diagnosis of pheochromocytoma is required for appropriate perioperative medical and anaesthetic management to prevent life threatening complications.
