Biophysical basis of skin cancer margin assessment using Raman spectroscopy.

Biomed Opt Express 2019 Jan 7;10(1):104-118. Epub 2018 Dec 7.

Department of Biomedical Engineering, The University of Texas at Austin, 107 W. Dean Keeton Street C0800, Austin, TX 78712, USA.

Achieving adequate margins during tumor margin resection is critical to minimize the recurrence rate and maximize positive patient outcomes during skin cancer surgery. Although Mohs micrographic surgery is by far the most effective method to treat nonmelanoma skin cancer, it can be limited by its inherent required infrastructure, including time-consuming and expensive on-site histopathology. Previous studies have demonstrated that Raman spectroscopy can accurately detect basal cell carcinoma (BCC) from surrounding normal tissue; however, the biophysical basis of the detection remained unclear.

Spatial analysis of p63, K5 and K7 defines two groups of progenitor cells that differentially contribute to the maintenance of normal sebaceous glands, extraocular sebaceous carcinoma and benign sebaceous tumors.

J Dermatol 2019 Jan 21. Epub 2019 Jan 21.

Institute for Hematopathology, Hamburg, Germany.

The histogenesis of extraocular sebaceous carcinomas is - in contrast to ocular sebaceous carcinomas - unclear, and information about the exact cellular architecture of these lesions and even of the normal sebaceous gland is still scarce. This study attempts to elucidate the histogenesis of sebaceous tumors, using multicolor immunofluorescence stainings to analyze 21 cases of sebaceous tumors (six each of extraocular sebaceous carcinoma, sebaceous adenoma and sebaceoma, and three cases of steatocystomas) and eight cases of normal sebaceous glands for p63, several keratins, androgen receptor, adipophilin, epithelial membrane antigen (EMA) and Ki-67. The data of this observational study provide evidence for the existence of two subpopulations of progenitors in normal sebaceous glands: (i) p63 K5 progenitors which generate the K10 luminal cells of sebaceous ducts; and (ii) p63 K5 K7 progenitors which finally generate K7 adipophilin EMA sebocytes.

MicroRNA and transcriptome analysis in periocular Sebaceous Gland Carcinoma.

Sci Rep 2018 May 14;8(1):7531. Epub 2018 May 14.

Department of Ocular Biology and Therapeutics, UCL Institute of Ophthalmology, London, UK.

Sebaceous gland carcinoma (SGC) is a rare, but life-threatening condition with a predilection for the periocular region. Eyelid SGC can be broadly categorised into two subtypes, namely either nodular or pagetoid with the latter being more aggressive and requiring radical excision to save life. We have identified key altered microRNAs (miRNA) involved in SGC shared by both subtypes, hsa-miR-34a-5p and hsa-miR-16-5p. Read More

Evaluation of universal immunohistochemical screening of sebaceous neoplasms in a service setting.

Clin Exp Dermatol 2018 Jun 14;43(4):410-415. Epub 2018 Jan 14.

East Anglian Medical Genetics Service, Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

Background: Muir-Torre syndrome (MTS) is a subtype of Lynch syndrome, which encompasses the combination of sebaceous skin tumours or keratoacanthomas and internal malignancy, due to mutations in DNA mismatch repair genes. Sebaceous neoplasms (SNs) may occur before other malignancies, and may lead to the diagnosis, which allows testing of other family members, cancer surveillance, risk-reducing surgery or prevention therapies.

Aim: To evaluate the efficacy of universal immunohistochemistry (IHC) screening of SNs in a service setting. Read More
