Background: Skin adnexal neoplasms are relatively rare and thus uncommonly encountered in routine pathology practice.
Aims: The present study was conducted with the aim to diagnose various skin adnexal tumors on fine-needle aspiration cytology (FNAC) followed by confirmation on histopathology and immunohistochemistry of the excised tumor.
Materials And Methods: A total of 11 cases of superficial nodular swellings of the skin were studied over a period of 2 years from 2015 to 2016. Read More

Hyaline cell-rich apocrine mixed tumor is relatively rare, and it often possesses atypical cells. Despite the presence of atypical cells, other histopathological features such as well circumscription, smooth border, predominance of bland cells, and no mitotic figures lead to classify these tumors as benign. In addition, no recurrence or metastasis has been reported even when cytologic atypia is identified. Read More

We present a very rare case of malignant chondroid syringoma of the fingertip in a 44-year-old man that was reconstruced by neurovascular island flap after the complete tumor resection of the fingertip. Although it is a rare tumor at an unusual area, it should be included in the differential diagnosis of the finger tumors. Read More

Aims: A number of homeobox transcriptional factors are utilised as organ-specific markers in the histopathological diagnosis of neoplasms. We have screened a homeobox gene that is expressed specifically in normal sweat gland cells and is useful for the histopathological diagnosis of sweat gland neoplasms.
Methods And Results: By screening an open database resource of The Human Protein Atlas, 37 genes among the 235 homeobox transcriptional factors were found to be expressed specifically in the skin. Read More

Collision or contiguous tumors, defined as two or more distinct tumors occurring at one site, are often an unexpected finding and may represent a diagnostic challenge, as clinical and histological presentations do not always coincide. Various combinations of collision tumors have been described with respect to melanocytic lesions, with the most frequently reported being the combination of nevus and basal cell carcinoma. We present an unusual case on the nose involving a melanoma in situ and a clinically-inapparent syringoma, which, to the best of our knowledge, is the first report of this combination. Read More

Clinically, MAC in the periocular area has been misdiagnosed as basal cell carcinoma, squamous cell carcinoma, or even chalazia. Read More

Mixed/biphasic tumors include epithelial-myoepithelial tumors, pleomorphic adenoma, matrix-producing tumors, cutaneous mixed tumors such as chondroid syringoma (CS), malignant mixed tumors (carcinosarcomas), pulmonary blastomas (in lung), and many others. Morphology may show overlap between various mixed tumors. At any particular site, whether these tumors are primary or metastasis from other sites is difficult to determine, more so if primary is unknown or not disclosed. Read More

Eruptive syringoma is an unusual variant of syringoma, which usually presents before or during puberty. It typically occurs in large numbers as multiple yellow-brown-colored papules, which may show spontaneous regression. Because some authors have proposed that it could present as a reactive process of eccrine ducts to an inflammatory reaction caused by an unknown trigger, the exact pathomechanism is still unclear.

Syringomas are benign adnexal tumors that are characterized histologically by the presence of small solid and cystic epithelial structures in the upper half of the reticular dermis. Reflectance confocal microscopy is a noninvasive diagnostic method that enables in vivo visualization of tissues with a resolution that approximates that of conventional histopathology. The use of this method in skin imaging over the past several years has improved dermatological diagnoses, creating the potential for its wide application in such diagnoses, especially for benign and malignant skin tumors.

A 38-year-old woman is described who presented with a slowly growing mass on the posterior aspect of the left ear. Excision and histopathologic evaluation revealed a pleomorphic adenoma (PA) originating from heterotopic salivary gland tissue. Many authors have presented cases of PAs originating from ceruminous glands in the external auditory canal or of so-called chondroid syringoma originating from apocrine and eccrine sweat glands.
