Plaque Type Syringoma

Abstract

Special types of syringoma include eruptive syringoma (1) and syringoma on the vulva and on the upper extremities (2). We present a large one, 1×5 cm in size, found on the right side of the neck, and preoperatively diagnosed as nevus sebaceus.

A Case of Unusual Syringoma: Unilateral Linear Distribution and Plaque Formation

“…Localized syringomas with unusual clinical features include cases developing in rare areas such as the genitalia, neck, or trunk and those showing a unilateral linear distribution or plaque formation (1)(2)(3)(4)(5). Kikuchi et al (1) first reported a case of plaque type syringoma.…”

“…Occasionally, other areas, including the anterior chest, trunk, neck, and external genitalia, are also affected (1)(2)(3)(4)(5).…”

Carbon Dioxide (CO2) Laser Vaporization of Multiple Facial Syringomas

“…An uncommon plaque type has also been described. 26 First described in 1872 by BiesiadeckiZ7 and Kaposi," and called lymphangioma tuberosum multiplex, these tumors are histologically composed of small ductal structures lined by two rows of epithelial cells. These ducts lie within a fibrous dermal stroma and may become elongate and take the shape of a tadpole or comma.…”

Sweat duct proliferation associated with aggregates of elastic tissue and atrophodermia vermiculata: a simulator of microcystic adnexal carcinoma. Report of two cases†

“…This is an uncommon variant that may easily be misdiagnosed as MAC 9 . This rare type of syringoma was first described in 1979 by Kikuchi et al 10 A total of nine cases have been reported, most of them localized on the neck or face, the onset ranging from 6 to 78 years. Clinically, solitary brownish lichenoid plaques about 1 to 7 cm in size have been described.…”
