A 65-year-old man was referred to our hospital for the treatment of a lesion on the medial lacrimal canthus of both eyes. He had a history of perinuclear anti-neutrophil cytoplasmic antibodies, i.e., pANCA-positive interstitial pneumonia. Orbital magnetic resonance imaging excluded space occupying lesions, and laboratory testing excluded thyroid-related diseases. The masses were excised, and hi...

BACKGROUND Ocular sebaceous carcinoma is an uncommon, aggressive ocular neoplasm with potential for regional and distant metastasis. CASE PRESENTATION A 77-year-old woman was found to have a solitary pulmonary lesion 6 years after the initial treatment of sebaceous carcinoma of the eyelid. Video-assisted lung wedge resection of an undetermined pulmonary nodule was carried out successfully. Mi...

Sebaceous adenoma of the salivary gland is a rare tumor comprising 0.1% of all salivary gland neoplasms and less than 0.5% of salivary adenomas. Histologically, sebaceous adenomas are benign neoplasms consisting of sebaceous cells arranged in nests forming acinar and duct-like structures. Oncocytic metaplasia may also occur in some areas. We describe a case of sebaceous adenoma in the submandib...

A recent large-scale retrospective study has revealed that the frequency and aggressiveness of extraocular sebaceous carcinoma is comparable with that of the periocular counterpart (1) and a signiflcant number of extraocular sebaceous carcinomas show regional and widespread métastases (2). However, sentinel lymph node (SLN) biopsy has seldom been used for identifying regional nodal metastasis i...

Angiomatoid fibrous histiocytoma (AFH) is a rare, lowgrade malignant soft-tissue tumor most commonly occurring in the extremities of children and young adults and has a low potential of local recurrence and metastasis. Here, we present a case of recurrent subcutaneous perianal AFH. After an initial diagnosis as a sebaceous cyst, we were able to use immunohistochemical findings to correctly iden...

Mitochondria are not difficult to demonstrate in sebaceous cells. Yet, they are only briefly described in the literature. Nicholas et al (4) believed that mitochondria in sebaceous cells undergo a direct transformation into lipid droplets. In the sebaceous glands of the mouse the mitochondria are said to increase in number at the beginning of lipid storage, to decrease during sebaceous transfor...

Nevus sebaceous is a congenital, benign hamartomatous lesion, characterized by a yellowish to skin-colored, hairless, verrucous plaque on the head and neck region. In later life, a secondary tumor, either benign or malignant, can develop within nevus sebaceous. Eccrine poroma developing on nevus sebaceous is extremely rare. There are few case reports of eccrine poroma developing within nevus se...

This case report details of a case of cutaneous metastasis from a primary adenocarcinoma of the oesophagus to the right cheek. A 67-year-old male was referred to the maxillofacial department with a 2-3 week history of non-painful swelling of the cheek. A diagnosis of infected sebaceous cyst was made and drainage was attempted with adjunctive antibiotic therapy. Follow up appointments showed no ...
