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.

“…Las feohifomicosis tienen distribución mundial, sin embargo, es más frecuente encontrar casos cutáneos en climas tropicales y subtropicales (2,9,10). Los hongos causantes de la enfermedad son agentes cosmopolitas, pero algunas especies tienen distribución limitada como Rhinocladiella mackenziei en Medio Oriente, Veronaea botryosa y Fonsecaea monophora al Sur de China.…”

“…Los factores predisponentes incluyen trasplantados de órganos y médula ósea, terapias con esteroides, trauma, abuso de drogas intravenosas, neutropenia, leucemias, uso crónico de catéteres, sinusitis crónica e infección por virus de inmunodeficiencia humana (2,11). En casos superficiales y subcutáneos tipo quiste micótico la mayoría de los pacientes son inmunocompetentes (9,10).…”

ResumenLas feohifomicosis comprenden un grupo de infecciones causadas por hongos pigmentados, negros o dematiáceos. En las últimas dos décadas se ha incrementado la frecuencia de reportes y la diversidad de los agentes etiológicos implicados, especialmente en los individuos inmunosuprimidos. Los principales géneros involucrados incluyen Alternaria, Bipolaris, Cladophialophora y Exophiala. Estos hongos típicamente se encuentran en el suelo y son introducidos al cuerpo a través de la inhalación o el trauma. El espectro de las enfermedades asociadas también se ha ampliado e incluye infecciones cutáneas superficiales y profundas, enfermedad alérgica, neumonía, abscesos cerebrales e infección diseminada. El diagnóstico de laboratorio está basado en las características morfológicas de los agentes según lo observado en el examen microscópico directo y la histopatología. El tratamiento es a menudo difícil y depende del síndrome clínico. No hay terapias estandarizadas, pero voriconazol, posaconazol e itraconazol han demostrado la actividad in vitro más consistente contra este grupo de hongos. La rareza de estas micosis justifica describir las características clínicas, epidemiológicas y diagnósticas para ayudar a un reconocimiento inmediato y un tratamiento oportuno.Palabras clave: Feohifomicosis, Dematiáceos, Feohifomicosis subcutánea, Infecciones oportunistas, Agentes antifúngicos. AbstractPhaeohyphomycosis comprises a group of infections caused by black pigmented or dematiaceous fungi. In the last two decades the frequency of reporting and diversity of etiologic agents involved have increased, especially in immunosuppressed individuals. The main genera involved include Alternaria, Bipolaris, Cladophialophora and Exophiala. These fungi are typically found in the soil and introduced through inhalation or trauma. The spectrum of associated diseases also has broadened and includes superficial and deep cutaneous infections, allergic disease, pneumonia, brain abscess and disseminated infection. The laboratory diagnosis is based on the morphological characteristics of the agents as observed by direct microscopic examination and histopathology. Treatment is often challenging and depends upon

The panniculitides comprise a group of heterogeneous inflammatory diseases that involve the subcutaneous fat. Histopathological study is required for the specific diagnosis of these disorders, because different panniculitides usually show the same clinical appearance – which typically consists of erythematous nodules on the lower extremities. However, the histopathological study of panniculitis is difficult because of the poor correlation between clinical and pathological findings and the changing microscopic appearances as the lesions evolve. Furthermore, large scalpel incisional biopsies are required in order to evaluate panniculitis fully. From the histopathological point of view, all panniculitides are somewhat mixed, because the inflammatory infiltrate involves both the septa and lobules. However, differentiation between a predominantly septal and a predominantly lobular panniculitis is usually straightforward at scanning magnification on the basis of which subcutaneous structures are the more intensely involved by the inflammatory infiltrate.
