ABSTRACT
Eruptive vellus hair cyst (EVHC) is a rare follicular developmental abnormality of the vellus hair follicles. The usual onset is between 17 and 24 years but may be congenital. It can arise sporadically or may be inherited in an autosomal dominant fashion. They are caused by an abnormality at the infundibular level of vellus hairs. They usually appear as yellow to reddish-brown papules over the chest, limbs, and abdomen. Histologically, cyst has a stratified squamous epithelium and it contains lamellated keratin and several vellus hairs. We present this rare case of a 12-year-old male because of its unusual morphology and distribution and also to generate awareness about this rarely diagnosed condition. To the best of our knowledge, no case of an axillary variant of EVHC has been reported till date.
ABSTRACT
CONTEXT: Patients with dermatological problems have higher prevalence of psychiatric illnesses than the general population. Melasma, hyperpigmentation of skin over sun-exposed areas, has bidirectional cause-effect relationship with depression and stress through psycho-neuro-endocrine pathways. AIMS: The aim of this study is to study the psychiatric morbidity and perceived stress in patients with melasma and statistically compare objective study parameters with those without melasma. SETTINGS AND DESIGN: This cross-sectional descriptive study was carried out in Tertiary hospital in urban setting, jointly by psychiatrist and dermatologist. METHODS AND MATERIALS: The study involved 50 consecutive patients with melasma and 30 relatives of patients coming to dermatology clinic not having any skin disorder. Cases were assessed by psychiatrist as per the International Classification of Diseases-10 Diagnostic Criteria for Research, Cohen's 4 item perceived stress scale, Disability Assessment Scale 2.0 by WHO and Hospital Anxiety Depression Scale (HADS) and Dermatologist calculated melasma area severity index score (MASI). RESULTS: Majority patients were females (88%) in the reproductive age group. The most common psychiatric morbidity seen in 42% cases was major depressive disorder. Adjustment disorder (26%) was the second most common diagnosis. Nonparametric analysis using Mann-Whitney U test revealed significantly more perceived stress (P = 0.001), more disability (P = 0.000) and anxiety-depression on HADS (P = 0.0 16) in cases than in their relatives. LIMITATIONS: This was a hospital-based study and thus melasma patients in the community are not represented. Small sample size, less number of controls, lack of structured diagnostic interview are other limitations of this study. CONCLUSIONS: There is high psychiatric comorbidity (76%) of depressive and stress disorders, higher functional disability and perceived stress in patients with melasma compared to controls.
ABSTRACT
Cryptococcosis is an opportunistic infection caused by Cryptococcus neoformans that typically presents in immunocompromised patients, most commonly in those with human immunodeficiency virus (HIV) infection. It rarely has been described in patients with diabetes mellitus (DM). Defects in the host defense mechanisms due to hyperglycemia predispose diabetic patients to opportunistic infections such as cryptococcosis. We present a rare case of disseminated cryptococcosis in a 48-year-old HIV-negative man with DM.

UNLABELLED: Platelet-rich plasma (PRP) has become a newer method for the treatment of various types of alopecia. In this prospective study, safety, efficacy and feasibility of PRP injections in treating androgenic alopecia were assessed. Eleven patients suffering from hair loss due to androgenic alopecia and not responding to 6 months treatment with minoxidil and finasteride were included in this study. The hair pull test was performed before every treatment session. A total volume of 2-3 cc PRP was injected in the scalp by using an insulin syringe. The treatment was repeated every two weeks, for a total of four times. The outcome was assessed after 3 months by clinical examination, macroscopic photos, hair pull test and patient's overall satisfaction. RESULTS: A significant reduction in hair loss was observed between first and fourth injection. Hair count increased from average number of 71 hair follicular units to 93 hair follicular units. Therefore, average mean gain is 22.09 follicular units per cm(2.) After the fourth session, the pull test was negative in 9 patients. CONCLUSION: PRP injection is a simple, cost effective and feasible treatment option for androgenic alopecia, with high overall patient satisfaction.
ABSTRACT
Lichen sclerosus et atrophicus (LSA) is a rare, chronic, mucocutaneous disease of unknown cause. Onset can occur in subjects of any age but more prevalent in adult females around the time of menopause. In both the sexes anogenital involvement is more common. Extragenital cases are rare, and common localizations are neck and shoulders, axilla, upper arms, flexor aspects of wrists and around the umbilicus. Bullous LSA is an unusual manifestation of the disease. Isolated extragenital bullous LSA is a distinctly rare event with very few cases reported till date.
ABSTRACT
Eruptive vellus hair cysts were first described in 1977. They usually appear as yellow to reddish-brown papules on the chest. Usual onset is between ages 17 and 24 years, but they may be congenital. Some believe that they may be inherited as an autosomal dominant disorder. Histologically the cyst has a stratified squamous epithelium and it contains laminated keratin and vellus hairs. They are felt to be caused by an abnormality at the infundibular level of the vellus hair. We present this because of this patient's unusual distribution of eruptive vellus hair cysts.
ABSTRACT
Melanoacanthoma is very rare variant of seborrheic keratosis presenting as a deeply pigmented benign proliferation of melanocytes and keratinocytes usually presenting over the head, neck and trunk of elderly people. A sixty-two-years-old male was presented with a solitary slow growing asymptomatic hyperpigmented verrucous outgrowth with cerebriform surface measuring 15 cm by 8 cm present over the left inguinal region extending on to the scrotum since past 8 years. There was no associated lymphadenopathy. The histopathology revealed hyperkeratosis, papillomatosis, acanthosis with presence of melanocytes at all levels of epidermis with abundant melanin giving the diagnosis of melanoacanthoma. The patient further underwent surgical excision of the lesion. The case is being reported for its rarity, unusual location, massive size and clinical resemblance to a verrucous carcinoma.
ABSTRACT
Piedra is a superficial fungal infection of the hair shaft characterized by nodules along the hair shaft. Black piedra affects the scalp hair more frequently than white piedra. Occurrence of both types of piedra simultaneously in a patient is extremely rare. We describe here a rare case of mixed piedra of scalp hair.
ABSTRACT
Four types of elastosis perforans serpiginosa (EPS) have been described in literature: 1) idiopathic EPS, 2) reactive perforating elastosis associated with connective tissue disorders, 3) in some instances of pseudoxanthoma elasticum (PXE), disease-specific calcified elastic tissue is extruded, producing a clinical picture indistinguishable from other types, may also be seen in patients undergoing hemodialysis and 4) EPS induced by long-term treatment with D-penicillamine is observed in patients suffering from Wilson's disease. Long term D-penicillamine therapy causes an alteration in the dermal elastic tissue. D-penicillamine induced EPS has a distinctive histopathologic feature - serrated appearance of elastic fibers due to perpendicular budding from their surface giving a "lumpy-bumpy" look. D-penicillamine induced elastic fiber alteration may not always manifest clinically as EPS. We report a case of D-penicillamine induced widespread alteration in skin elastic tissue with distinct histopathologic features.

Subcutaneous phaeohyphomycosis is an infection of the skin and subcutaneous tissue, caused by dematiaceous fungi. An adult male presented with a history of multiple reddish nodules over the face and hands. Histopathological examination of the skin biopsies showed a dense granulomatous infiltrate of macrophages, containing intracytoplasmic basophilic bodies throughout the dermis. Gomori methenamine-silver stained sections revealed yeast cells within macrophages. Multiple cultures on Sabouraud's dextrose agar grew Cladophialophora boppii. The patient was treated with oral itraconazole for a year and the response monitored with dermal ultrasound. This is the first case report of subcutaneous phaeohyphomycosis caused by Cl. boppii in India.
