Onychomycosis is a fairly common condition seen in a dermatology clinic. Dermatophytes Trichophyton and Epidermophyton are the known filamentous fungi implicated. The yeast-like fungi such as Candida less commonly cause Onychomycosis. The genus Prototheca may on preliminary observation resemble yeast-like fungi but a detailed microscopy will reveal the absence of budding and presence of endospores. Onychoprotothecosis is an uncommon presentation of human protothecosis. Of the two Prototheca species (Prototheca zopfii and Prototheca wickerhamii) known to cause the disease, P. wickerhamii has been reported more commonly. We report a culture proven case of this condition caused by P. zopfii. The patient, a 55-year-old housewife presented with discolouration and breaking off of the right thumb and forefinger nails since a period of six months. Samples of nail scrapping sent to the Microbiology Laboratory were culture-positive for Prototheca. Speciation by the automated Vitek-2 system (bioMerieux) identified the isolate as P. zopfii, which was further confirmed at PGI, Chandigarh.

Abstract-Chromoblastomycosis is a fungal infection of the cutaneous and subcutaneous tissues. It is non contagious and chronic fungal infection. Several species of pheoid or dematacious fungi which are saprophytes are the causative agents. Infection occurs when the causative agent enters the body with trauma especially with wood splinters or thorn pricks. Diagnosis is done by demonstration of sclerotic bodies or Medlar bodies in KOH mounts and histopathological examination, culture on Sabourauds agar and by Molecular and Serological methods. Case Presentation: A 50 year old male patient presented with. multiple plaques over the scalp and on the nape of the neck over the last 1 month, It was associated with itching. He did not give any history of injury but carried wood on his head and shoulders. The condition was diagnosed as Tinea capitis and skin scrapings sent for microscopic examination and fungal culture. Laboratory diagnosis.The diagnosis of Chromoblastomycosis by Fonsecaea. compacta (F. compacta) was made based on the finding of sclerotic bodies in KOH mounts and characteristic growth on SDA. Conclusions:-Chromoblastomycosis presenting as a plaque like lesions should be considered as it may be confused with other superficial dermatic lesions.
