Chromomycosis or chromoblastomycosis is a chronic deep skin mycosis that affects the skin and subcutaneous tissue and is caused by fungi from the Dematiaceae family, which are imperfect fungi that produce pigments similar to melanin. Several species are known to cause chromoblastomycosis; all have low virulence and produce similar clinical manifestations. The most common species is Fonsecaea pe...

An unusual case of chromoblastomycosis is reported, it resembled dermatophytosis, tinea faciei due to the presence of a well-demarcated scaly ery- thematous patch on the face. The patient was a 63-year-old farmer from central Thailand, who had the skin lesion for 10 years. Mycological and histopathologi- cal investigations of scales and skin biopsy specimen revealed a granulomatous infiltrate w...

An experimental study was conducted between January 2002 and April 2003 for the detection of delayed hypersensitivity to Fonsecaea pedrosoi metabolic antigen (chromomycin) in skin tests. A total of 194 subjects were attended by spontaneous demand at the Infectious and Parasitic Diseases outpatient clinic of the Federal University of Maranhão-UFMA and at the Department of Microbiology, Federal U...

Chromoblastomycosis is a chronic human melanized fungi infection of the subcutaneous tissue caused by traumatic inoculation of a specific group of dematiaceous fungi through the skin, often found in barefooted agricultural workers, in tropical and subtropical climate countries. We report the case of a male patient presenting a slow-growing pruriginous lesion on the limbs for 20 years, mistreate...

We report a fatal case of a chromoblastomycosis-like infection caused by a novel species of Fonsecaea in a 52-year-old immunocompetent Caucasian male from an area of chromoblastomycosis endemicity in Brazil. The patient had a 30-year history of slowly evolving, verrucous lesions on the right upper arm which gradually affected the entire arm, the left hemifacial area, and the nose. Subsequent di...

We report herein a case of chromoblastomycosis caused by Fonsecaea (F.) pedrosoi in a 39-year-old male, who showed multiple, asymptomatic, scaly erythematous plaques on the left shin for 12 months. Histopathologically, chronic granulomatous inflammation and either sclerotic or muriform cells were observed. The fungal culture produced typical black colonies of F. pedrosoi. The DNA sequence of th...

Chromoblastomycosis is caused by dematiaceous fungi. It develops after inoculation of the organism into the skin. The lesion begins as a pink, scaly papule or warty growth. We report a case of chromoblastomycosis occurring in a multibacillary leprosy patient, who had already been released from treatment (RFT). The diagnosis was confirmed by the presence of sclerotic bodies (Medlar bodies / copp...
