    Biointerphases 2018 Jan 12;13(3):03B402. Epub 2018 Jan 12.
    Department of Chemistry and Molecular Biology, University of Gothenburg, Gothenburg 412 96, Sweden.
    A set of basal cell carcinoma samples, removed by Mohs micrographic surgery and pathologically identified as having an aggressive subtype, have been analyzed using time-of-flight secondary ion mass spectrometry (SIMS). The SIMS analysis employed a gas cluster ion beam (GCIB) to increase the sensitivity of the technique for the detection of intact lipid species. The GCIB also allowed these intact molecular signals to be maintained while surface contamination and delocalized chemicals were removed from the upper tissue surface. Read More

    The limitations of dermoscopy: false positive and false negative tumors.
    J Eur Acad Dermatol Venereol 2018 Jan 5. Epub 2018 Jan 5.
    First Department of Dermatology, Aristotle University, Thessaloniki, Greece.
    Dermoscopy has been documented to increase the diagnostic accuracy of clinicians evaluating skin tumors, improving their ability to detect skin cancer and better recognize benign moles. However, dermoscopically "false positive" and "false negative" tumors do exist. False positive diagnosis usually leads to unnecessary excisions. Read More

    Case report repairing orbital skin defects using composite flaps after giant eyelid-derived tumor excision and orbital exenteration.
    Medicine (Baltimore) 2017 Dec;96(48):e8978
    Department of Ophthalmology, Second Hospital of JiLin University, ChangChun.
    Rationale: Though giant malignant tumors arising in the eyelid are rare, they often require extensive surgery for removal along with orbital exenteration. Because of this, repairing orbital defects is an important factor in the surgical strategy.

    Patient Concerns: Case 1 was a 78-year-old nomad man who presented in the Department of Ophthalmology with a giant tumor in his right eyelid, which had developed over three years. Read More

    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.
