cylindroma

 [sil″in-dro´mah]
a benign skin tumor, usually on the face and scalp consisting of cylindrical masses of epithelial cells surrounded by a thick band of hyaline material. adj., adj cylindrom´atous.

cyl·in·dro·ma

(sil'in-drō'mă),
A histologic type of epithelial neoplasm, frequently malignant, characterized by islands of neoplastic cells embedded in a hyalinized stroma that may represent a thickened basement membrane; may form from ducts of glands, especially in salivary glands, skin, and bronchi; in the salivary glands, also termed adenoid cystic carcinoma.
Synonym(s): cylindroadenoma

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. Cylindromas are often associated with trichoepitheliomas, especially on the scalp (turban tumour), first develop in adolescence and rarely undergo malignant degeneration.

cyl·in·dro·ma

(sil'in-drō'mă)
Slow growing, infiltrative tumor frequently found in submaxillary and parotid salivary glands and accessory glands of the palate. Chief histologic feature is presence of uniform, small dark-staining basal cells in anastomosing cords, with acellular areas between.

On review of literature, Billroth in 1859 first used the term 'cylindroma' to describe the histologic appearance of this tumor.
Clinically, cylindromas present as red nodules that are sometimes painful.
Histologically, cylindromas consist of blue, basaloid, geometric micronodules of tumor cells in the dermis without epidermal connection.
Recent investigations regarding cylindroma tumorigenesis have confirmed that activation of MYB, in either wild-type forms or in fusion derivatives, is common in both spontaneous and hereditary cylindromas [19, 20].
Adenoid cystic carcinomas contain intrinsic basement membrane material, albeit in a different configuration than in cylindromas (Figure 6).
Ashworth, "Inherited cylindromas: Lessons from a rare tumour," The Lancet Oncology, vol.
INTRODUCTION: Cylindromas are benign skin appendageal tumors most commonly occurring on head, neck and scalp.
Hereditary Conditions.--Multiple cylindromas (socalled turban tumor) are seen in familial cylindromatosis (Brooke-Spiegler syndrome), which is inherited in an autosomal dominant fashion.
Multiple cylindromas accompanied by spiradenomas or trichoepitheliomas or both are found in inherited syndromes, such as Brooke-Spiegler syndrome, familial cylindromatosis, and multiple familial trichoepithelioma syndrome.
In 1859 Bilroth gave it a description of pathology and coined the term "cylindroma" and also made a note of its tendency to recur.
