Sialadenoma papilliferum is a rare tumor, primarily of minor salivary gland origin, first described by Abrams and Finck (Cancer 24:1057-63, 1969). It is both an exophytic and endophytic papillary lesion histologically resembling syringocystadenoma papilliferum of sweat gland. The tumor is considered benign although rare recurrent cases have been reported. Three cases of malignant transformation...

We report a new case of p63/cytokeratin 7 (CK7) positive syringocystadenocarcinoma papilliferum (SCACP), on the shoulder of an 88-year-old man, with superficial dermal infiltration and squamoid differentiation. We describe the 24th case of SCACP, the malignant counterpart of syringocystadenoma papilliferum (SCAP). At the present, we do not know whether SCACP arises from eccrine or apocrine glan...

We present a case of poroid hidradenoma on the right chest in a 62year-old male with diabetes mellitus and chronic renal failure. Poroid hidradenoma is usually solitary and shows eccrine differentiation. There have been a small number of reports describing poroid hidradenoma, and the present case is a rare instance. Because the relations between clear cell neoplasms and diabetes mellitus are kn...

Vulval fibroadenoma is an extremely rare entity seen in women of the age group 20-80 years. Only 50 cases ectopic benign mammary tissue have been reported medical literature, with vulva being second most common extra-mammary site. We report a case 44 years old female, para 2 live 2, who presented initially endophytic swelling her for 6-7 months, which became exophytic since associated pain 1 mo...

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...

Nodular hidradenoma is a rare benign tumour of eccrine sweat gland. It usually presents as a solitary, intradermal nodule 0.5 -2 cms in diameter in most instances. It may be red, brown or bluish and sometimes may show superficial ulceration. We are presenting a case report of 50 years old female who presented with painless swelling measuring 3×3 cms over right leg for 2 years. Excisional biopsy...

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...

The predisposition to epithelial neoplasms in nevus sebaceous is well established; most tumors occur in adults and are benign. Hidradenoma is a relatively rare benign tumor of sweat gland origin that can rarely arise within a nevus sebaceous. We present an interesting case of a hidradenoma and sebaceoma arising within a nevus sebaceous and present a literature review of the 2 conditions. Even t...

BACKGROUND Appendageal skin tumors belong to a heterogenous group of tumors with specific histopathology. The aim of this study is to determine the pattern of appendageal tumors in skin biopsies done in our department. METHODS This is a 3-year retrospective descriptive study of all patients who were diagnosed to have skin appendageal tumors in our department, and the diagnoses were confirmed ...
