Dermal cylindroma is a common benign adnexal skin tumor. The most common location is scalp (almost 60% of cases) but the tumors may also be seen on the trunk and extremities. Rare locations include orbit, ear canal, abdomen, and breast. There is a marked female predilection.

In pathology, a cylindroma is a tumour with nests of cells that resemble a cylinder in cross section.

These disorders have an autosomal dominant inheritance, meaning half of an affected individual’s children will also have the condition. Dermal cylindroma. These two tumors are very closely related and overlap. Many tumors have areas of both spiradenoma and cylindroma. The lobules of cylindroma are small more consistently discrete, show more a more consistent arrangement of the light and dark cells and are; often surrounded by prominent hyaline material. Malignant cylindroma can occur in the Brooke-Spiegler syndrome, and malignant transformation is more frequent in multiple variants than in solitary tumors. Its histopathological basis is controversial, and its origin is unknown, although it is known that there is a genetic basis for onset of these tumors in Brooke-Spiegler syndrome.

In dermatologic pathology, a dermal cylindroma, also dermal eccrine cylindroma or Cutaneous Cylindroma) and (less specifically) cylindroma, is a benign adnexal tumor, which occurs on the scalp and forehead.when multiple Cylindroma-Show Hat like configuration. 2009-09-02 · Cylindroma of the breast is a very rare lesion which is morphological and immunophenotypically identical to benign dermal cylindroma. We report a breast cylindroma in a previously healthy 62 year old female detected through a national breast screening program.

Brooke-Spiegler syndrome, familial cylindromatosis and multiple familial trichoepitheliomas are due to germline mutations in the cylindromatosis (CYLD) gene on chromosome 16q12. These disorders have an autosomal dominant inheritance, meaning half of an affected individual’s children will also have the condition.

Eccrine and apocrine naevi are rare malformations of the glandular component of an eccrine or apocrine gland.The glands within a sweat gland naevus are increased in size and number from birth. Eccrine naevi produce either a mucinous discharge or a localized area of excessive sweating (hyperhidrosis), which can occur spontaneously or following provoking factors such as heat Malignant cylindroma can occur in the Brooke-Spiegler syndrome, and malignant transformation is more frequent in multiple variants than in solitary tumors.

Cylindromas are uncommon benign adnexal tumor. Multiple cylindromas are commonly genetically inherited and also known as "turban tumor." Cytology of dermal cylindroma is rarely discussed in previous literature.

Spiradenoma and cylindroma are related sweat gland tumors. To delineate their histogenesis, gene profiles, and their potential drivers, we performed a whole-transcriptome sequencing analysis of fourteen samples of spiradenoma/cylindroma in comparison to normal samples.

cylindroma A benign skin adnexal tumour, seen on the face, trunk and extremities, which has apocrine differentiation. Cylindromas may be solitary (and sporadic or multiple) with an autosomal dominant hereditary pattern.

1 The term Pathology: Microscopically, dermal cylindromas are composed of multiple tumor lobules arranged in a jigsaw pattern. The lobules are typically surrounded by a rim of PAS-positive basement membrane material and are composed of undifferentiated basaloid tumor cells. The histogenesis of dermal cylindroma is controversial. Sweat gland naevus. Eccrine and apocrine naevi are rare malformations of the glandular component of an eccrine or apocrine gland.The glands within a sweat gland naevus are increased in size and number from birth.

The results from Fehr et al., 2011 indicate that MYB oncogene activation through gene fusion is an important pathogenetic mechanism that may contribute to cylindroma tumorigenesis.
