Cutaneous infection by Syncephalastrum.

Cutaneous infection of the thumb by a Syncephalastrum sp. is described in an adult male suffering from diabetic ketosis. The fungus was isolated from the skin and was found to produce arteritis in the dermal vessels. The patient died of diabetes mellitus without any associated systemic mycosis. Syncephalastrum in this case had occurred as an opportunistic infection.

Trichophyton simii infection due to laboratory accident.

Trichophyton simii produced kerion on the intact forearm skin due to a laboratory accident within 5 days of contact. Early institution of griseofulvin resolved the condition in 15 days with no recurrence during 38 months of follow-up.

Adiaspiromycosis of human skin caused by Emmonsia crescens.

Two cases of cutaneous adiaspiromycosis by Emmonsia crescens are reported. This is the first human skin infection by this species and is the first report of its kind in man from India. In the first patient, the agent was demonstrated in KOH mounts, histology and culture from irregular, pigmented skin plaques on the right gluteal area. The lesion also contained calcium. In the second patient the fungus was demonstrated histologically in a knee lesion. The agent had elicited a histiocytic and giant cell reaction in the dermis in both cases. The first patient suffered from anaemia and epilepsy and the second suffered from nephropathy with chyluria. The skin lesions were surgically excised with skin grafting in the first patient.

Lymph node invasion by Conidiobolus coronatus and its spore formation in vivo.

Lymph node invasion with presence of conidia, their replicates, germ tubes, condidia with hair-like projections and hyphae have been observed in a case of entomophthoromycosis caused by Conidiobolus coronatus. This rare occurrence of conidia with hair-like projections that is usually observed in vitro, has been observed in vivo, in the content of an abscess produced by this agent, C. coronatus in the present case. Severe disfigurement and destruction of facial and nasopharyngeal tissues, have also been observed in this case. Response to therapy with oral KI, surgery, combinations of trimethoprim and sulphamethoxazole and steroids though found useful initially, was ineffective subsequently as the disease progressed over 7 years. Findings of lymphatic invasion and the extensive destruction observed in the present case warrants a guarded prognosis. Free conidial reproduction found in lymph nodes may suggest the possibility of this disease being infectious, requiring an active and vigorous treatment schedule and control measures in this infection.

An unusual presentation of Trichophyton violaceum infection.

A case with encapsulated Tricophyton violaceum abscesses in the skin is recorded. Defective cell mediated immunity was shown in the patient and his two cousins. This defect combined with malnutrition, hypoadrenalism and griseofulvin resistance gave unusual lesions and chronicity. A probable genetic factor for the defective cell mediated immunity is postulated.

Cutaneous infection by Cryptococcus laurentii.

Cryptococcus laurentii was isolated twice from cutaneous granulomas in the leg and foot of a 40-year-old man. Histologically the cells of C. laurentii were found in groups in the dermis and also inside giant cells. There was epithelioid cell infiltration in the dermis and subcutis. An atypical mycobacterium was isolated in addition to C. laurentii. Therapy with anti-tuberculous drugs after an initial amphotericin B infusion was found to be satisfactory.

A study of 3891 cases of mycoses in the tropics.

4103 cases suspected of mycoses were analysed as to sex, age and site of disease and 3891 were proved cases. This group formed 50% of total mycoses or 13-93% of all dermatoses recorded in the Government General Hospital, Madras, during the period of study. There were 66-26% adult female, 27-6% adult male and 6-14% were below 13 years. Dermatophytoses were found in 73-5%; the other common diseases were tinea versicolor (17-68%) and candidiasis (12-43%). Multiple sites of involvement or more than 1 disease in the same individual were mostly observed. The incidence of piedra (0-1%) and deep mycoses (0-156%) was very low. Mycetoma was the common disease (5/6) in deep mycoses. In dermatophytoses, tinea corporis (49-71%) and tinea cruris (47-85%) commonest; tinea axillaris (3-42%), tinea capitis (1-72%) and tinea barbae (1-29%) were less common. The incidence of tinea manuum, tinea pedis and tinea unguium was similar (4-97%-6-38%). High temperature and humidity were related to the higher incidence of tinea corporis, tinea cruris and tinea versicolor. Mainly children suffered from tinea capitis. All other mycoses were commonly found in adults between 2nd and 3rd decades. In all mycoses but candidiasis, female predominated. Cutaneous candidiasis was mainly a problem of housewives. Among the dermatophytes Trichophyton violaceum was predominant (33-7%) followed by T. rubrum (32-6%). Trichophyton schoenleinii and M. gypseum were rarely isolated. From mycetoma, Madurella mycetomii, Nocardia braziliensis, N. asteroides and Actinomadura spp. were isolated. Demonstration of Cryptococcus laurentii in 1 case is reported in this area for the first time.
