Linear syringocystadenoma papilliferum of the thigh

Dermoscopy of a rare case of linear syringocystadenoma papilliferum with review of the literature

Syringocystadenoma papilliferum (SCAP) is a benign hamartomatous tumor arising from pluripotent cells with either apocrine or eccrine differentiation. We report a rare case of de novo linear SCAP in a 12-year-old female child with lesions over the chest along with the dermoscopic findings.

Neighboring look-a-likes: distinguishing between breast and dermatologic lesions

Due to the proximity of the skin, subcutis, and axilla to the breast, the possibility of a "breast mass" actually representing a dermatologic lesion should be considered, particularly if the proliferation does not look characteristically "mammary" in appearance. Even more underappreciated is the scenario of a dermatologic proliferation morphologically masquerading as a breast tumor. The pathologist can fall prey to this pitfall if he/she is led to believe that the location of the tumor is the breast proper. The aim of this review is to provide an overview of dermatologic mimickers of breast lesions and helpful ways to discern between them when possible.

A case of zonal syringocystadenoma papilliferum of the axilla mimicking verruca vulgaris

Syringocystadenoma papilliferum (SCAP) most frequently arises from an organoid nevus on the head and neck. Zonal or segmental lesions occurring in other locations are rare. Here, we report a case of a 39-year-old woman with an SCAP clinically mimicking verruca vulgaris in a zonal distribution on her right axilla after her birth. Histopathologic examination showed it to be a typical SCAP. Furthermore, the tumor had a warty surface, which histologically revealed some signs of viral infection. Although polymerase chain reactions for low- and high-risk human papilloma virus types were negative, the relationship of SCAP with viral infection needs further investigation.

[Atypical presentation of syringocystoadenoma papilliferum]

Syringocystoadenoma papilliferum is benign adnexal tumor derived from the sweat glands that is located in the head and neck in 70-80% of patients, and commonly presents as a papule or a solitary nodule. We report a case of syringocystoadenoma papilliferum with an atypical presentation given its location in the thigh and the peculiar histologic features, unrepresentative of this entity.

Syringocystadenoma papilliferum: report of the first case on the lower leg

Syringocystadenoma Papilliferum (SCAP) is a benign adnexal tumor which most frequently arises from an organoid nevus on the head and neck. Although they are rarely found on the trunk and limbs, we treated a case of this disorder on the lower leg. A 26-year-old man had an asymptomatic tumor on his lower leg. Histopathological examination showed it to be a typical SCAP on organoid nevus. This is the first report of SCAP on the lower leg.

Syringocystadenoma papilliferum: an unusual cutaneous lesion in a pediatric patient

We report a case of syringocystadenoma papilliferum, a rare cutaneous adnexal neoplasm, occurring synchronously in two distinct unusual locations in a 22-month-old child with lesions on the lower leg and back.
