Apocrine nevus is a rare benign tumor of which only 9 cases have been reported in the literature. The apocrine nevus is seen mostly in the areas where the apocrine glands are normally distributed such as axillae, head and neck. Our case was a 16-year old girl who referred with a verrucous erythematous plaque over right parietal side of the scalp. The patient had the plaque since birth with part...
Syringocystadenoma papilliferum is an uncommon benign apocrine gland tumour, mostly of congenital or early childhood onset, affecting head and neck. In addition, nevus sebaceous is commonly associated with this tumor. Here, we document three cases of syringocystadenoma papilliferum with many atypical features, such as the involvement of rare sites (abdomen, axilla and thigh), absence of nevus s...
Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors witho...
Syringocystadenoma papilliferum (SCAP) is an uncommon benign adnexal tumor of the skin. It is frequently seen in association with other benign adnexal lesions, such as nevus sebaceous, apocrine nevus, tubular apocrine adenoma, apocrine hidrocystoma, apocrine cystadenoma, and clear cell syringoma. The unusual reported locations of SCAP include the head and neck, the buttock, the vulva, the scrot...
Nevus sebaceus of Jadassohn is a congenital cutaneous hamartoma comprised of multiple skin structures. It has the potential to develop into variety of neoplasms of various epidermal adnexal origins. While multiple tumors may occasionally arise, it is unusual for more than four tumors to arise simultaneously within a single sebaceus nevus. Here in, we report a case of a 70-year-old woman with si...
A malignant transformation is known to occur in many nevi such as a sebaceous nevus or a basal cell nevus, but a verrucous epidermal nevus has only rarely been associated with neoplastic changes. Keratoacanthoma, multifocal papillary apocrine adenoma, multiple malignant eccrine poroma, basal cell carcinoma and cutaneous squamous cell carcinoma (CSCC) have all been reported to develop from a ver...
During the normal development of skin, pluripotential cells give rise to keratinocytes, sebaceus glands, hair follicles, apocrine glands and eccrine glands. A hamartoma, or an abnormal mixture of a tissue’s normal components, results from an error in development, among which some show malignant potential. We report two Chinese cases of giant congenital cutaneous hamartoma, a nevus sebaceus of J...
First Reported Case of 'Epidermal Nevus Syndrome' with a Triad of Central Nervous System Deformities
Epidermal nevus syndrome (ENS) is a term used to describe the occurrence of an epidermal nevus in association with other extra-cutaneous developmental anomalies, most commonly involving the nervous and musculoskeletal systems. The nevus is classified on the basis of the main component which may be keratinocytic, sebaceous, follicular, apocrine, or eccrine. Most patients who present with ENS is ...
Nevus sebaceous is known by its association with one or more secondary tumors, but more than three multiple tumors arising from a nevus sebaceous is extremely rare. A 67-year-old female presented with a light brown plaque on the back of her head that contained a dome-shaped black node and an erosive lesion. Histopathological examination showed atypical basaloid cells in the black node. At the p...
Apocrine hydrocystoma (AH) typically presents a translucent, skin-colored to bluish dome shaped cyst on the face, although it occurs in other sites [1]. It is not uncommon and occurs in adult life with no predilection for particular age group. Males and females are equally affected [2]. AH mimics basal cell carcinoma (BCC), blue nevus, amelanotic melanoma requiring histopathological confirmatio...
