    Basal Cell Carcinoma of Vermilion Mucosa of Upper Lip: a Rare Case Report.
    Acta Med Indones 2017 Jul;49(3):255-258
    Department of Dermatology, Jundishapur University of Medical Sciences, Ahvaz, Iran.
    Although basal cell carcinoma (BCC) is a common skin tumor, very rare cases of BCC arising from upper vermilion mucosa of lip have been reported previously. This tumor basically, originates from pillar structures and the involvement of the vermilion lip contrasts this concept so it is devoid of hair follicles and sweat glands. The exact pathogenesis of vermilion lip BCC is not clear but it has been postulated that the neoplasm originates from the pluripotential epithelial cells of the oral mucosa and epidermis. Read More

Clinically, MAC in the periocular area has been misdiagnosed as basal cell carcinoma, squamous cell carcinoma, or even chalazia. Read More

    Sebaceous carcinoma in situ as a concept and diagnostic entity.
    Dermatol Pract Concept 2017 Jul 31;7(3):27-31. Epub 2017 Jul 31.
    Departments of Pathology and Dermatology, Hofstra Northwell School of Medicine, Hempstead, NY, USA.
    Although carcinoma in situ has been accepted as a well-established concept and diagnostic category, for reasons unknown sebaceous carcinoma in situ has not been recognized yet in general pathology or dermatopathology. Such lesions have always been misinterpreted as either benign neoplasm or sebaceous carcinoma. In the present essay, we provide a convincing account supporting sebaceous carcinoma in situ as a valid concept and diagnostic entity via critical literature review and histopathological assessment and illustration.

    Purpose: To determine the prognostic value of the staging criteria for eyelid tumors in the 7th edition of the American Joint Committee on Cancer (AJCC) staging manual and to determine, for each type of eyelid tumor, which AJCC T categories are associated with increased risk of nodal metastasis and thus potential usefulness of sentinel lymph node biopsy.

    Methods: Systematic review and analysis of articles found by searching PubMed and Google Scholar using the search terms "AJCC," "eyelid," "carcinoma," and "melanoma."

    Results: Rates of local recurrence, regional nodal metastasis, and distant metastasis were approximately 7% to 10%, 1% to 9%, and 0% to 0. Read More
