Chondroid Syringoma

Chondroid syringoma: A rare lid tumor

“…This tumor was first described by Billroth[5] and the term chondroid syringoma was coined by Hirsh and Helwig to characterize the origin from sweat glands[6] though the appearance is like pleomorphic adenoma of lacrimal gland. A proper histopathological examination to rule out presence of normal lacrimal gland tissue external to the tumor capsule helps to differentiate chondroid syringoma.…”

A Mixed Tumor of the Skin of the Nose

“…It is possible for the tumor to be diagnosed incorrectly as ectopic salivary' gland mixed tumor as is demonstrated in the report of Fendall [9], Though the studies of Lennox et al [6], Stout and Gorman [1] and Ilirsch and Helwig [2] comprising 55, 134 and 188 cases, respectively, failed to disclose any evidence of malignancy in a mixed tumor of the skin, malignant change and even metastasis have been described [10,11]. Careful examination of the salivary glands is essential as well, taking into account the report of a case by Giltman et al [ 12], in which for the first time a scalp nodule was diagnosed as the primary manifestation of the malignant nature of the parotic tumor.…”

“…It is generally assumed that these tumors develop from sweat glands [1] , Mixed tumors of the skin are also designated as chondroid syringoma [2] and mucinous hidradenoma [3], terms with more descriptive than histogenetic significance.…”

“…Apart from the studies of Lennox et al [6], Stout and Gorman [1] and Hirsch and Helwig [2], only isolated cases have been reported. The skin of the head and face is most commonly involved; the lesions occur, in descending order of frequency, on the skin of the nose, cheek, upper lip, scalp, forehead and chin [2].…”

“…The skin of the head and face is most commonly involved; the lesions occur, in descending order of frequency, on the skin of the nose, cheek, upper lip, scalp, forehead and chin [2]. Fewer than 40 cases involving the skin of the nose have been reported hitherto.…”
