Novel meso-substituted porphyrin derivatives and its potential use in photodynamic therapy of cancer.

BMC Cancer 2021 May 13;21(1):547. Epub 2021 May 13.

Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP), CONICET and Hospital de Clínicas Gral. José de San Martín, Universidad de Buenos Aires, Córdoba 2351 1er subsuelo, CP1120AAF, Ciudad de Buenos Aires, Argentina.

Background: Photodynamic therapy (PDT) is an anticancer treatment that utilizes the interaction of light and a photosensitiser (PS), promoting tumour cell death mediated by generation of reactive oxygen species. In this study, we evaluated the in vitro photoactivity of four meso-substituted porphyrins and a porphyrin coupled to a fullerene.

Methods: The cell line employed was the LM3 mammary adenocarcinoma, and the PS with the best photokilling activity was administered to mice bearing the LM3 subcutaneously implanted adenocarcinoma. Read More

Papillary Renal Cell Carcinoma in Lynch/Muir-Torre Syndrome with Germline Pathogenic Variant in and Molecular Analysis: Report of a Case and Review of the Literature.

J Kidney Cancer VHL 2021 21;8(2):8-19. Epub 2021 Apr 21.

Department of Pathology & Immunology.

Lynch syndrome (LS) is an autosomal dominant inherited disorder due to pathogenic variations in the mismatch repair genes, which predisposes to malignancies, most commonly colon and endometrial carcinoma. Muir-Torre syndrome is a subset of LS with cutaneous sebaceous adenoma and keratoacanthoma in addition to the malignancies. Renal cell carcinoma (RCC) in patients with LS is extremely rare.

Treatment-resistant actinic keratoses are characterized by distinct clinical and histological features.

Ital J Dermatol Venerol 2021 Apr;156(2):213-219

Faculty of Health, University Witten-Herdecke, Witten, Germany.

Background: Actinic keratoses (AK) are generally treated to reduce the risk of progression into invasive cutaneous squamous cell carcinoma (cSCC). However, this risk of transformation is low, and rather than focusing on these lesions, current treatment studies report on complete clearance of AKs in an entire field. This study aimed to investigate treatment-resistant AKs (trAK) after field therapy compared to randomly chosen AKs prior to treatment. Read More

Sebaceous Gland Carcinoma of Lid: Masquerading as a Recurring Chalazion.

Int J Appl Basic Med Res 2021 Apr-Jun;11(2):117-119. Epub 2021 Apr 8.

Department of Ophthalmology, All India Institute of Medical Sciences, Bhubaneswar, Odisha, India.

Recurrent chalazion may be associated with bad lid hygiene but can have clinical changes which lead to the suspicion of a more dangerous entity. Particularly in elderly patients, recurrence of chalazion should be suspected to have carcinomatous changes. We present the case of a 52-year-old woman with presentation of recurrent chalazion which turned out to be sebaceous gland carcinoma of the lid. Read More

Isolated peripunctal sebaceous gland carcinoma in a young adult: An unusual presentation.

Saudi J Ophthalmol 2020 Jan-Mar;34(1):73-75. Epub 2020 Nov 22.

Ophthalmic Pathology Laboratory, L V Prasad Eye Institute, Kallam Anji Reddy Campus, Road No. 2, Banjara Hills, Hyderabad - 500 034, Telangana, India.

Sebaceous gland carcinoma (SGC) of the eyelid is one of the leading peri-ocular eyelid malignancies in Asian-Indians. It usually affects elderly women and has a high rate of local recurrence, regional and distant metastasis. This is partly attributable to a delay in clinical diagnosis since it mimics more benign conditions of the eyelid like chalazia. Read More

In cis TP53 and RAD51C pathogenic variants may predispose to sebaceous gland carcinomas.

Eur J Hum Genet 2021 Mar 15;29(3):489-494. Epub 2020 Dec 15.

Institute of Human Genetics, University of Leipzig Medical Center, 04103, Leipzig, Germany.

Pathogenic variants in TP53 have been classically thought to cause Li-Fraumeni syndrome (LFS), a cancer predisposition with high risks for various childhood- and adult-onset malignancies. However, increased genetic testing has lately revealed, that pathogenic variant carriers exhibit a broader range of phenotypes and that penetrance may be dependent both on variant type and modifiers. Using next generation sequencing and short tandem repeat analysis, we identified germline pathogenic variants in TP53 and RAD51C located in cis on chromosome 17 in a 43-year-old male, who has developed a rare sebaceous gland carcinoma (SGC) but so far no tumors of the LFS spectrum.

Department of Dermatology, Hospital do Servidor Público Estadual de São Paulo, São Paulo, SP, Brazil.

Muir-Torre syndrome is a rare, autosomal dominant genodermatosis, characterized by sebaceous neoplasms and visceral carcinomas. The authors describe the case of a patient who, 16 years after the diagnosis of colon carcinoma, presented a verrucous plaque on the pubic region, histopathologically compatible with sebaceous adenoma. The need to investigate this syndrome is emphasized, especially in cases of sebaceous neoplasms located outside the head, face, and neck. Read More
