ABSTRACT
Dermatophytes are fungi capable of invading keratinized tissues. Isolation of the fungus with the culture is essential to guide the treatment, because there are more resistant species like Microsporum canis. The chronic use of corticosteroids leads to the deregulation of immunity, promoting atypical manifestations of infections. Topical antifungal therapy is often insufficient, requiring systemic medications. We describe the case of a patient undergoing systemic corticosteroid therapy with a large figurate lesion who presented complete response to exclusively topical treatment.

A doença de Paget extramamária é neoplasia cutânea rara, ocorrendo tipicamente na vulva de mulheres caucasianas na pós-menopausa. Clinicamente, o sintoma mais comum é o prurido, observando-se lesão eritematosa, descamativa e eczematosa. Devido à raridade da doença e a sua aparência inespecífica, pode ser confundida com outras condições dermatológicas, retardando o diagnóstico. O presente caso demonstra uma forma de doença de Paget extramamária vulvar unilateral confirmada por estudo anatomopatológico e imunohistoquímico. O tratamento-padrão da doença é cirúrgico, e a paciente foi submetida à exérese completa da lesão, continuando em acompanhamento semestral.
Extramammary Paget's disease is a rare cutaneous neoplasm typically occurring in the vulva of Caucasian women after menopause. Clinically, the most common symptom is pruritus, when an erythematous, desquamative and eczematous lesion can be observed. Due to the rarity and nonspecific appearance of the disease, it can be confused with other dermatological conditions, delaying diagnosis. The present case demonstrates a form of vulvar extramammary unilateral Paget's disease confirmed by anatomical pathologic and immunohistochemical study. The standard treatment used for the disease in this case was surgical and the patient underwent complete excision of the lesion, with continued monitoring every six months.
ABSTRACT
Macular amyloidosis is a form of cutaneous amyloidosis characterized by dusky-brown lesions usually located on the upper back between the shoulder blades. This report describes the case of a 45 year-old female presenting with hyperpigmented macules and lace-like, non-pruritic erythema in the sacral and cervical region as well as on both arms and legs. Histology revealed amyloid deposits in the papillary dermis which exhibited apple-green birefringence after Congo red staining. There were no systemic findings. This is a case of macular amyloidosis with an unusual presentation. The literature on the subject is also reviewed.

A amiloidose macular é uma forma cutânea primária de amiloidose, caracterizada tipicamente por máculas acastanhadas, acometendo predominantemente a região interescapular. O presente caso é o de uma mulher de 45 anos, há um ano com manchas hipercrômicas, rendilhadas e não pruriginosas, em membros superiores, região cervical, sacral e membros inferiores. No estudo histopatológico da biópsia de pele, foi evidenciada substância amiloide amorfa no topo das papilas dérmicas, que se tornou mais evidente após a coloração pelo vermelho Congo. Não havia alterações sistêmicas associadas. Além da localização atípica e extensa da amiloidose cutânea macular, o presente caso procura acrescentar dados para esclarecimento do tema.
