      Abstract: development of squamous cell carcinoma from sebaceous cyst is uncommon.in this report , we report a77- old female patient who has had a sebaceous cyst for 20 years. The cyst started to grow during the last year. The patient underwent an operation for excision biopsy and The diagnosis was squamous cell carcinoma.

We experienced two cases of cutaneous dermoid cysts (DC). To elucidate the histogenesis of DC, we have studied cytokeratin (CK) expression in DC using ten different anti-keratin antibodies against CK1, 7, 8, 10, 14, 15, 16, 17, 18 and 19, and anti-filaggrin (filament aggregating protein) antibody. In the cyst wall of DC, CK1 and 10 were expressed in suprabasal layer, and CK14 was limited to the...

CONTEXT Lymphoepithelial cysts with sebaceous glands of the pancreas are extremely rare, with only 7 cases, including this case, published in English literature. CASE REPORT We herein present the case of a 67-year-old Asian man who underwent a resection of a lymphoepithelial cyst of the pancreas during the follow up care for lung cancer. Fourteen years previously he underwent a right lower lo...

BACKGROUND Lymphoepithelial cyst (LEC) of the pancreas is a rare benign tumor. LEC with sebaceous glands of the pancreas is extremely rare, and its histogenesis remains unclear. CASE PRESENTATION We present a 66-year-old man with an incidental finding of a cystic lesion at the neck of the pancreas. Pancreatic juice cytology results and elevated serum carbohydrate antigen 19-9 and Dupan-2 leve...

BACKGROUND Strengthening primary care is the focus of many countries, as national healthcare systems with a strong primary care sector tend to have lower healthcare costs. However, it is unknown to what extent general practitioners (GPs) that perform more services generate fewer hospital referrals. The objective of this study was to examine the association between the number of surgical interve...

Rudolf Virchow is considered to be the first scientist to have used the word sebaceous cyst. It was thought that these lesions occurred due to retention of sebaceous secretion consequent to obstruction of sebaceous ducts of sebaceous glands, although that was found not to be the case. In all these cysts, the cavity is filled with keratin. There are six types of keratin-filled cysts, namely, epi...

A 25-year-old man presented with a painless, nontender, nonerythematous sublingual mass that had gradually increased in size over the preceding 2 years. Fine-needle aspiration biopsy was nondiagnostic. During the week following our evaluation, the mass became increasingly painful and swollen, and it severely impaired his speech and swallowing. Magnetic resonance imaging demonstrated a sharply d...

Epidermoid cyst is commonly known as sebaceous cyst. It is the most commonly encountered cyst of the skin. Epidermoid cyst over the breast is uncommon. Punctum is the hallmark for clinical diagnosis. Local excision with primary closure is the treatment of choice. Biopsy is mandatory in giant cyst to exclude malignancy.
