Primary cutaneous actinomycosis.

Actinomycosis is a chronic, progressive, suppurative infection, prevalent over the neck, thorax or abdomen. As it rarely occurs with few clinical symptoms, its diagnosis requires a high index of clinical suspicion. We report a case of primary cutaneous actinomycosis affecting the back.

Ecthyma gangrenosum in a new born child.

Ecthyma gangrenosum is one of the most serious and specific cutaneous infection caused by Pseudomonas aeruginosa. We report a case of ecthyma gangrenosum in a new born child who responded poorly to the antipseudomonas treatment to highlight the poor prognosis in new born.

Phaeoacremonium krajdenii, a cause of white grain eumycetoma.

We describe the first case of white grain pedal eumycetoma caused by Phaeoacremonium krajdenii in a 41-year-old man from Goa, India. Based on histological examination of biopsy tissue showing serpentine granules, a culture of the granules yielding phaeoid fungal colonies, and morphological characteristics and sequence comparison of the partial beta-tubulin gene with the ex-type isolate of P. krajdenii, the causal agent was identified as P.

White grain mycetoma caused by a Cylindrocarpon sp. in India.

We describe a case of white grain eumycetoma of the foot of an Indian male caused by a slow-growing, poorly sporulating fungus that does not match any known agent of this infection. Histologic examination of a biopsy tissue specimen showed oval, lobular, white granules composed of hyaline, septate hyphae, and thick-walled chlamydospores. Culture of granules from a draining sinus yielded compact, very-slow-growing, poorly sporulating colonies producing a strong reddish brown pigment that diffused into the medium.

Mycobacterium fortuitum in cutaneous infections.

Three cases of culture proven primary cutaneous infections caused by Mycobacterium fortuitum, a rapidly growing non tuberculous mycobacterium, are reported. The first case was treated with ciprofloxacin and the other two, with trimethoprim / sulphamethoxazole with an excellent outcome.

A Case of Tinea Nigra From South India.

Tinea nigra in the axillar-y region of a south Indian youth is reported. A KOH mount of the scrapings showed typical fungal elements and the culture yielded Exophiala Werneckii.
