Along with that there was prominent chondrosarcomatous areas (Figure 1E and 1F) and extensive squamous metaplasia with formation of numerous epidermal cysts
of keratinous type (Figure 1G).
Minimal incision suction-assisted excision of a large epidermal cyst
Diagnosis of a small epidermal cyst
that occurs in the subcutaneous tissue is usually straightforward, but enlarged cysts presenting in the breast parenchyma require them to be differentiated from other benign or malignant breast lesions.
An epidermal cyst
is a firm slow-growing lump underneath the skin1.
1,3,4) The major discrimination of keratinous cyst from epidermal cyst
is the higher potential of recurrences and the need for more aggressive surgical repair in the management.
should also be considered in diagnosis of inguino-labial swellings, which can be of huge size with chronic duration and can be asymptomatic.
In the literature, cases of steatocystoma simplex misdiagnosed as sebaceous cyst, dermoid cyst, epidermal cyst
, chalazion, and lipoma have been reported.
The differential diagnosis includes indirect inguinal hernia, endometriosis of the round ligament, inguinal lymphadenopathy, volvovaginal cysts and tumors, such as Bartholin's cyst or abscess, leiomyoma, lipoma, sarcoma, and epidermal cyst
The differential diagnosis of cyclist's nodule includes abscess, epidermal cyst
, lipoma, and benign and malignant tumours.
of the bony external auditory canal.
Here we present an unusual case of an epidermal cyst
arising in the intersphincteric plane of the anal canal.
Retention or epidermal cyst
is relatively common around the auricle, especially in the postauricular sulcus and lobule because it is rich in sebaceous glands.
10,14] Chondroid syringoma may be confused clinically with epidermal cyst
, dermatofibroma, pilomatricoma, neurofibroma, histiocytoma, seborrheic keratosis, calcifying epithelioma and basal cell carcinoma.
2] Associated epidermal cyst
in fibroadenoma of breast is also very rare.
Pathology report revealed a cyst with a lining of stratified squamous epithelium with granular layer with luminal content of laminated keratin material suggestive of an epidermal cyst
