RESUMEN
Abstract We report a 74-year-old male presented to an outpatient dermatology clinic in Manaus, Amazonas, with a one-year history of pruritic, keloidal lesions on his left lower extremity. Histopathology showed round structures in reticular dermis. Grocott methenamine silver stain revealed numerous round yeasts with thick double walls, occurring singly or in chains connected by tubular projections. The diagnosis was lobomycosis. Although the keloidal lesions presented by this patient are typical of lobomycosis, their linear distribution along the left lower limb is unusual.

Purpose: Teledermatology has emerged as an important tool to extend the reach of dermatologists. As utilization of teledermatology services increases, careful attention should be given to the design of the system for consulting dermatologists. Methodology: In this case study, we report how access to a patient's entire medical history in a teledermatology consultation was vital for an accurate diagnosis. Results: This case emphasizes the importance of full access to patients' medical records for improving diagnostic accuracy. We believe that full-access systems will lower the risk of misdiagnosis and will help to maximize the potential of teledermatology.

Leprosy is now considered in Western Europe as a strictly imported disease. A case of presumed locally acquired diffuse lepromatous leprosy was observed in a native-Portuguese woman living in France who developed an acute febrile presentation with extensive cutaneous signs.

Rare molds are increasingly emerging as a cause of deep and invasive fungal infections. We report here a rare case of cutaneous phaeohyphomycosis of the lower limbs due to Alternaria alternata associated with extra-ungual localization of Scopulariopsis brevicaulis. Diagnosis was made based on repeated, direct, microscopic mycological and histological examinations. The study revealed hyphae and fungal cells in a granulomatous dermal infiltrate. Identification of the molds was based on macroscopic appearance on culture of samples from the lesions on Sabouraud's dextrose agar and microscopic appearance on Lactophenol cotton blue following slide culture.
