How to diagnose nonpigmented skin tumors: A review of vascular structures seen with dermoscopy

Aspectos dermatoscópicos do siringocistoadenoma papilífero associado a nevo sebáceo

“…10 There are few cases published in the literature on dermoscopy of adnexal tumors and these refer to eccrine poromas, hidradenomas and angiohistiocytomas. [8][9][10] Therefore, up to the present time little is known on dermoscopy in cases of syringocystadenoma papilliferum and nevus sebaceus.…”

“…10 There are few cases published in the literature on dermoscopy of adnexal tumors and these refer to eccrine poromas, hidradenomas and angiohistiocytomas. [8][9][10] Therefore, up to the present time little is known on dermoscopy in cases of syringocystadenoma papilliferum and nevus sebaceus. Dermoscopy of a nevus sebaceus shows roundshaped structures of a yellowish-white color, grouped together or presenting singly, which may correspond to clusters of mature, superficial sebaceous glands.…”

“…7 Reports have been published on the dermoscopic pattern of adnexal tumors such as eccrine poromas, hidradenomas and angiohistiocytomas. [8][9][10] Nevertheless, up to the present moment, there has been no description of dermoscopy carried out to evaluate syringocystadenoma papilliferum. The present report describes the clinical investigation, dermoscopy and histopathology of a case of syringocystadenoma papilliferum associated with a nevus sebaceus and syringoma in a 50-year old woman.…”

Dermoscopy of pigmented papillated Bowen disease: A report of two cases

“…1 As pigmented papillated Bowen disease has hyperkeratosis, papillomatosis and basal melanosis histologically, its dermoscopic features can be confusing due to the difficulty of recognizing the characteristic vascular structures and surface scales of conventional Bowen disease without using dermoscopy. 2,3 On the other hand, pigmented papillated Bowen disease shows no characteristic structures, such as milia-like cysts, comedo-like openings and a brainlike appearance, which are major components of seborrheic keratosis seen with dermoscopy, as in our two cases. 4,5 In conclusion, we describe the dermoscopic features of pigmented papillated Bowen disease and suggest that irregular fissures/ridges and structureless brown areas may be critical dermoscopic features of pigmented papillated Bowen disease to differentiate it from seborrheic keratosis.…”

Arteriovenous malformation after punch biopsy clinically mimicking a basal cell carcinoma: Case report and review of literature

“…One case report describes blue‐red lacunae, milky red areas, red ovoid areas, winding red vessels of several thicknesses, and some dotted vessels 10. Whereas BCC's are well described in the literature as arborizing vessels (94.1% positive predictive value) with shiny red‐white structureless areas 11, 12. Although differentials exist, identifying these vascular patterns will aid in the diagnosis.…”
