“…The black dots seen on the surface of the lesions are a consequence of damaged connective tissue, foreign matter, and the fungal etiologic agents in the dermis being expelled through the epidermis [8,9]. Both patients described here had cerebriform lesions studded with black dots, which was suggestive of chromoblastomycosis.…”

Chromoblastomycosis is a chronic subcutaneous mycosis commonly caused by Fonsecaea, Phialophora, and Cladophialophora spp. Out of these, Fonsecaea pedrosoi is the most common etiological agent, implicated in 70%-90% of the cases reported worldwide. The histopathological diagnosis of chromoblastomycosis is based on visualization of medlar or sclerotic bodies in the tissue. These sclerotic bodies divide by planar division. Rarely, budding is seen in these sclerotic bodies. As this entity can be confused with phaeohyphomycosis, it is important to be aware of such a presentation also. We report two cases of chromoblastomycosis that showed budding sclerotic bodies.

“…Transepidermal elimination in chromoblastomycosis was originally studied by Batres et al (1978) when those authors were conducting a histopathological review of two cases of the disease and observed the presence of fungal structures in the stratum corneum (Figure 4). 17 The phenomenon of transepidermal elimination was confirmed in the patients in the present study.…”

BACKGROUND: Chromoblastomycosis is a chronic fungal infection caused by fungi from the Dematiaceae family. According to several studies, Fonsecaea pedrosoi is the most common of these fungi. The infection is more common in tropical countries, with the Brazilian state of Pará having one of the largest infected populations worldwide. The disease is difficult to treat and recurrences are common. OBJECTIVES: To describe the epidemiological and mycological aspects of cases of chromoblastomycosis and its clinical forms in the state of Pará, Brazil. METHODS: Mycological exams (direct mycological examinations, culture and microculture) were performed and a clinical/epidemiological evaluation was made of 65 patients receiving care at the Dermatology Department of the Federal University of Pará between 2000 and 2007. The clinical classification proposed by Carrión in 1950 was used in this study. RESULTS: The majority of the patients were male (93.8%), agricultural workers (89.2%) of 45 to 55 years of age, and the majority of lesions (55.4%) were of the verrucous type, located principally on the lower limbs (81.5%). In the majority of the cases investigated (61.5%), the infection had been present for a long time, with a mean duration of 11 years. Direct mycological examination was performed in 86.2% of the patients (n=56). Of these, 96.4% (n=54) tested positive. Culture and microculture were performed in vitro in 47 cases of those that tested positive at direct microscopy, results showing Fonsecaea pedrosoi to be the only agent present in this sample. CONCLUSION: This study highlighted the extent to which chromoblastomycosis still affects the quality of life of the local population, principally individuals working in agriculture. This is a chronic disease for which there is no effective treatment. The importance of continuing to investigate this disease should be emphasized, as further studies may lead to new clinical or epidemiological findings.

“…The lesions are usually located commonly in the hands, forearms and ankles. Transepithelial elimination, a spontaneously oc curring dermoepidermal phenomenon, is an important process in the pathology of chromoblastomycosis [16], and probably results in the 'black dots' found on the lesion surface [2], These contain the sclerotic bodies as well as clotted blood, medlar bodies, chromobodies, chlamydospores, copper pennies, and sclerotic bodies described by various other mycologists.…”

Chromoblastomycosis is a rare, deep mycosis seen mostly in tropical and subtropical regions. We have encountered a kidney transplant recipient with this subcutaneous mycosis developing as an asymptomatic mass in the right forearm. The lesion recurred after an initial local excision, but it is now apparently cured 10 months after wide surgical excision. The patient had previously been a shepherd. A 29-year-old kidney transplant recipient developed a rare deep chromoblastomycosis infection and was cured by aggressive diagnosis and surgical treatment.
