Disseminated cutaneous rhinosporidiosis.

Rhinosporidiosis is a chronic granulomatous disorder caused by Rhinosporidium seeberi. It frequently involves the nasopharynx and occasionally affects the skin. We herewith report a 55-year-old man who has disseminated cutaneous rhinosporidiosis. He presents with multiple reddish lesions over the nose of 10 year's duration. In the past year, he develops skin lesions over the right arm and over back. Histopathological examination of the skin biopsy specimen from the representative cutaneous lesions shows hyperplastic epithelium with numerous globular cysts of varying shape, representing sporangia in different stages of development. His serology for HIV infection by ELISA is negative. On the basis of these clinical and histopathological findings, a diagnosis of nasal rhinosporidiosis with cutaneous dissemination is made.

Reliable site for suction blister induction and harvesting.

BACKGROUND: Suction blister grafting is a useful modality of treatment of patients with resistant and stable vitiligo. However, there have been no detailed studies to find out the best donor site for blister formation. METHODS: The study was conducted between the period of October 2004 and February 2005 in the dermatology department at a tertiary care center. Nine patients with vitiligo (focal vitiligo, 3; mucosal vitiligo, 2; acrofacial vitiligo, 2; vitiligo vulgaris, 1; and segmental vitiligo, 1) were selected for blister harvesting and grafting. The blisters were raised using the method described by Gupta et al. RESULTS: Suction blisters were attempted to be raised at 52 sites, but only 38 blisters could be raised, 24 complete and 14 incomplete. Blisters were raised in all the three cases on the flexor aspect of the arm (100%), 15 of 17 cases (88.2%) on the flexor aspect of the forearm, 4 of 5 cases (80%) on the abdomen, 11 of 16 cases (68.7%) on the anterolateral thigh, and less frequently over leg or foot. Complete blisters were formed in 13/15 cases (86.6%) on the flexor aspect of the forearm, 6/11 cases (54.5%) on the anterolateral thigh, and in all cases over leg. CONCLUSION: The flexor aspect of the forearm is a good site for suction blister harvesting.

Clinical profile of molluscum contagiosum in children versus adults.

Molluscum contagiosum mainly affects children, but in adults the advent of HIV has modified its clinical spectrum. Our study is designed to ascertain the clinical profile of molluscum contagiosum in children and adults and to discover the effects of underlying HIV infection. During the study period of September 2000 to June 2002, 150 cases of molluscum contagiosum are screened and recruited at the Department of Dermatology and STD, JIPMER, Pondicherry. These include 137 children (85 male, 52 female) and 13 adults (10 male, 3 female). In children molluscum contagiosum is most commonly seen in the 5-10-year age group (58 cases), followed by the 1-5-year age group (53 cases), the 10-14-year age group (23 cases), and the younger-than-1-year age group (3 cases). In adults molluscum contagiosum is most commonly seen in the 14-20-year age group, followed by 2 cases each in the age groups 20-26 years, 26-34 years, and 34-40 years. The male-to-female sex ratio was 1.6:1 in children and 3.3:1 in adults. In both children and adults the most common sites affected are the head and neck, followed by trunk, upper extremity, genitalia, and lower extremity. It appears that the distribution of molluscum in our patients is significantly affected by the high proportion of HIV-positive adults in our sample. Seropositivity for HIV by ELISA is found in 1 of 137 children and 8 of 13 adults. In these HIV-positive patients, 2 cases of giant molluscum and one furuncle-like presentation are seen.

Cutaneous variant of angiokeratoma corporis diffusum.

A case of angiokeratoma corporis diffusum (ACD) involving the skin of a 22-year-old patient presenting with normal physical and mental development is reported. ACD presenting with skin lesions alone is a rare but specific clinical entity, which differs from hereditary sphingolipidoses such as Fabry's disease.

Lipoid proteinosis in two siblings: a report from south India.

A 6-year-old girl and her 9-year-old brother, born of nonconsanguineous parents, had hoarseness and multiple, asymptomatic, raised skin lesions present since childhood. On examination, both siblings had hoarseness and numerous skin-colored, waxy papules distributed over the forehead, face, neck, axilla, groin, and extremities. Acneiform (pocklike) scars were present on the face, trunk, and extremities. Eyelid beading (moniliform blepharosis) was present over bilateral upper and lower eyelids. The tongue, lips, and frenulum were thickened and infiltrated, and the patients were unable to protrude the tongue out of the mouth. The scalp had patchy alopecia. Histological examination of representative skin specimens (from both siblings) showed deposition of pink, amorphous material in the papillary dermis, around blood vessels, and around appendages. These deposits stained positive with Periodic Acid-Schiff stain, were diastase resistant, and were negative for Congo red, confirming our clinical diagnosis of lipoid proteinosis. Over 250 cases of this rare disorder have been described in the literature, but occurrence of lipoid proteinosis in siblings is rare.

Disseminated pheohyphomycosis.

A 40-year-old male agricultural laborer presented to our clinic with asymptomatic swellings on his left hand and left leg of 2 years' duration. A pea-sized swelling was first noticed on the back of the left hand, which was gradual in onset and slowly progressed to its present size. The patient later noticed multiple swellings over his left leg and thigh, with a similar progression. There was no history suggestive of inflammatory changes or discharge from the lesions. There was no previous history of trauma. The patient was an asthmatic and was on long-term oral steroid therapy (10-20 mg/day prednisolone). None of his family members had similar complaints. On physical examination, the patient was febrile. Cutaneous examination showed multiple, circumscribed, lobulated, non-tender, mobile, cystic swellings of various sizes, ranging from less than 2 cm over the left shin to more than 8 cm over the dorsum of the left hand and ankle (Fig. 1a,b). The surface over these swellings was shiny, smooth, and intact. The skin over the swellings was pliable and normal in color. There was no regional lymphadenopathy. The rest of the clinical examination was normal, except for decreased breath sounds over the left mid and lower pulmonary lobes. Routine laboratory tests, including complete blood count and liver and renal function tests, were within normal limits. Random blood glucose was greater than 400 mg%. Histopathologic examination of one of the cysts (from the hand) showed pheohyphomycotic cysts lined by dense fibrous tissue with chronic inflammatory infiltrate admixed with scattered giant cells in the dermis (Fig. 2). No fungal elements were visualized in the hematoxylin and eosin-stained sections. The fungal elements were found within the cystic cavity on special staining with Gomori's methenamine silver (GMS) and Masson-Fontana stains. The hyphae had irregularly placed branches and showed constrictions around their septae, thus resembling pseudohyphae and yeast forms (Fig. 3). Fine needle aspiration cytology from one of the swellings showed the presence of filamentous fungi on KOH examination and brown-pigmented distorted filaments and yeast-like cells on Masson-Fontana staining (Fig. 4a,b). The positive Masson-Fontana stain was indicative of the presence of melanin in the fungal hyphae, even when the fungal hyphae were not pigmented in the hematoxylin and eosin-stained section. Periodic acid-Schiff reagent also stained the fungal elements, thus confirming our diagnosis of pheohyphomycosis and ruling out the possibility of hyalohyphomycosis. The culture for fungus from the swelling aspirate grew contaminants. The chest X-ray showed dense nodular shadows in the left lower and mid pulmonary lobes. Sputum for acid-fast bacilli and Mantoux test were negative. During the hospital stay, the patient developed high fever and showed altered behavior, for which a computed tomography scan of the brain was performed; this showed evidence of multiple ring enhancing lesions in both frontal lobes. Ultrasound of the abdomen was normal. On the basis of the above findings, a diagnosis of disseminated subcutaneous pheohyphomycosis was made. The patient was given itraconazole, 100 mg twice daily, and his diabetes was managed with insulin. The fever stopped within a week and the altered behavior also started to show an improvement. There was obvious improvement in neurologic signs and symptoms. His skin lesions, however, responded slowly to the treatment. The patient did not report for further follow-up after 1 month.

Immunomodulators in the treatment of psoriasis.

The efficacy of cyclosporine and related drugs in the treatment of psoriasis was the key to the development of the concept that psoriasis is an immune mediated disorder. These therapies demonstrably reduce the number of activated T-lymphocytes, which correlates with clinical remission. Monoclonal antibodies directed against key components of the inflammatory process have been studied in an attempt to produce safer, more effective and selective immunosuppressive agents. This review summarizes the information available on cyclosporine and related drugs, and cytokine therapy, including monoclonal antibodies directed against T-cell mediated inflammation. It should be realized that biologic therapies for psoriasis are very new and that efficacy and safety information from clinical trials is just becoming available.

Papillary eccrine adenoma.

A 28-year-old man came to us with a solitary skin colored, mildly tender nodule of 6 months duration on the dorsum of the right hand. On histological examination, multiple dilated ducts without apparent continuity with the surface were found in the dermis. These dilated ducts had branching tubules with eosinophilic amorphous material filling most of the lumina. The peripheral cells of the tubules resembled myoepithelial cells, whereas the luminal border cells were cuboidal or low columnar. Papillary projections arising from the inner cells were seen extending into the lumen. These features were diagnostic of a rare tumor, papillary eccrine adenoma.
