Disseminated cutaneous leishmaniasis: lesional polymorphism and late diagnosis in an immunocompetent patient

Tegumentary leishmaniasis (TL) is considered a neglected tropical disease and it is endemic in Brazil. Among the wide morphological spectrum that composes TL, the disseminated cutaneous leishmaniasis (DL) stands out, which is characterized by multiple lesions in two or more non-contiguous body regions. This clinical form may be rarely associated with immunosuppression. The wide range of cutaneous manifestations is a remarkable DL feature, and its diagnosis may represent a challenge even for the specialists and experienced professionals. We report a case of an immunocompetent 55-year-old man, who has presented with polymorphic and disseminated skin lesions and he was treated incorrectly due to the absence of clinical suspicion of leishmaniasis.

Siringofibroadenoma écrino em paciente tetraplégico por mielite transversa / Eccrine syringofibroadenoma in a patient with quadriplegia following transverse myelitis

O siringofibroadenoma écrino (SFAE) é um tumor benigno raro que se origina das glândulas sudoríparas écrinas. Apresenta predileção pelas extremidades de indivíduos idosos e pode surgir em associação com várias doenças adquiridas ou hereditárias e com afecções cutâneas neoplásicas. Relatamos caso de homem de 48 anos, tetraplégico por mielite transversa há 30 anos, com tumoração plantar rapidamente progressiva de difícil diagnóstico

Eccrine syringofibroadenoma (EFAS) is a rare benign tumor that originates from the eccrine sweat glands. It has a predilection for the extremities of elderly individuals and may arise in association with various acquired or hereditary pathologies and neoplastic skin disorders. We report the case of a 48-year-old man who had been quadriplegic due to transverse myelitis for 30 years, with a rapidly progressive plantar tumor that was difficult to diagnose.

Erythematous papular rash after international travel

Bed bugs are hematophagous ectoparasites usually found in bedsteads mattresses, and sheets. The bed bug infestations have been increasing dramatically, but only a few cases have been reported in Brazil. We presented a case of a 49-year-old woman with diffuse, extremely itchy skin lesions, after she returned from an international travel.

Siringoma condroide: apresentação incomum de tumor raro / Chondroid syringoma: unusual presentation of a rare tumor

O siringoma condroide, também conhecido como tumor misto cutâneo, é uma neoplasia benigna rara, originada das glândulas sudoríparas, composta por estruturas epiteliais imersas em um estroma mixocondroide. Geralmente, apresenta-se como tumor sólido, único, localizado em face ou pescoço, com evolução crônica e assintomática. Relata-se caso de mulher, 75 anos, com lesão discretamente elevada na fronte, cujo diagnóstico foi definido pela análise histopatológica.

Chondroid syringoma, also known as a cutaneous mixed tumor, is a rare benign neoplasm originating from the sweat glands, composed of epithelial structures immersed in a myxochondroid stroma. It usually presents as a solid, single tumor located on the face or neck with a chronic and asymptomatic course. We report the case of a 75-year-old woman with a slightly elevated lesion on the forehead, whose diagnosis was defined by histopathological analysis.

Hamartoma folicular basaloide / Basaloid follicular hamartoma

O hamartoma folicular basaloide (HFB) é um tumor anexial raro e benigno, que se assemelha ao carcinoma basocelular (CBC), e pode apresentar manifestações clínicas diversas. Uma mutação no gene PTCH, envolvido na síndrome de Gorlin-Goltz, poderia estar associada à patogênese dessa neoplasia. Descreve-se caso de menina, sete anos, apresentando múltiplas pápulas na face.

Basaloid follicular hamartoma (BFH) is a rare and benign adnexal tumor that resembles basal cell carcinoma (BCC) and may present with different clinical manifestations. A mutation in the PTCH gene, involved in Gorlin-Goltz syndrome, could be associated with the pathogenesis of this neoplasm. We describe the case of a 7-year-old girl with multiple papules on her face.
