Chondroid syringoma of the nose: report of a case

Abstract

Chondroid syringoma or mixed tumour of the skin is a rare benign tumour which can present on the face. We present here the case of a patient who underwent an excisional biopsy of a small painless nodule in the soft triangle of the nose for cosmetic reasons. The clinical presentation, histology and treatment, with review of the relevant literature, is discussed.

Chondroid Syringoma: A Diagnosis More Frequent Than Expected

“…In all but one of our patients, the lesions were located on the head and neck region. Other predilection sites have been also reported in the literature, including the scrotum, eyelid, orbit, nose, foot, upper lip, forehead, axillary region, abdomen, penis, vulva, and scalp 3–10 . Because chondroid syringomas are rare and have silent clinical presentations, they are often overlooked and confused with other types of skin lesions such as dermoid or sebaceous cysts, neurofibromas, dermatofibromas, basal cell carcinomas, histiocytomas, pilomatricomas, and seborrheic keratosis.…”

“…Other predilection sites have been also reported in the literature, including the scrotum, eyelid, orbit, nose, foot, upper lip, forehead, axillary region, abdomen, penis, vulva, and scalp. [3][4][5][6][7][8][9][10] Because chondroid syringomas are rare and have silent clinical presentations, they are often overlooked and confused with other types of skin lesions such as dermoid or sebaceous cysts, neurofibromas, dermatofibromas, basal cell carcinomas, histiocytomas, pilomatricomas, and seborrheic keratosis. Although all of the reported cases in our series were benign lesions, also malignant examples of chondroid syringomas have been reported with a different clinical presentation than the relatively usual benign forms.…”

Benign chondroid syringoma: a confusing clinical diagnosis

“…Although their usual size is between 0.5 to 3.0 cm, giant tumors have been reported [4,5]. BCS have been reported in rare locations [2,6,9]. In this study the rate of occurrence in the head and neck was 76.90%.…”

Rare benign mixed tumour of the upper lip: A case report

“…CS have been observed in patients aged above 35 [3] , [13] , [14] , with a male predilection and a male-to-female ration of 2:1 [3] , [14] .…”

“…Due to the rare and unremarkable clinical presentation, CS can be overlooked and misdiagnosed as skin lesions such as dermoid or sebaceous cysts, neurofibromas, dermatofibromas, basal cell carcinomas, squamous cell carcinomas, histicoytomas, pilomatrixomas, and seborrheic keratosis [1] , [9] , [14] .…”
