Lymphangioma of the Lower Lip-A Diagnostic Dilemma: Report of a Rare Case with a Brief Literature Review.

Case Rep Dent 2022 2;2022:7890338. Epub 2022 Jun 2.

Department of Oral and Maxillofacial Pathology, Institute of Dental Sciences, Siksha 'O' Anusandhan University, Bhubaneswar, Odisha, India.

Hamartomas are tumor-like deformities typified by cellular propagation indigenous to the original site, although they display growth arrest without the possibility for further growth. Various hamartomatous oral lesions include hemangiomas, lymphangiomas, nevi, odontomas, Cherubism, etc. Lymphangiomas are benign, developmental hamartomatous entities typified by abnormal proliferation of lymphatic vessels.

Decoding a gene expression program that accompanies the phenotype of sporadic and Basal Cell Nevus Syndrome-associated odontogenic keratocyst.

J Oral Pathol Med 2022 Jun 4. Epub 2022 Jun 4.

Department of Oral Medicine & Pathology and Hospital Dentistry, School of Dentistry, National and Kapodistrian University of Athens, Athens, Greece.

Steroidogenic Factor-1 Lineage Origin of Skin Lesions in Carney Complex Syndrome.

J Invest Dermatol 2022 May 12. Epub 2022 May 12.

Institut Genetics, Reproduction & Development (iGReD), CNRS, Inserm, University of Clermont-Auvergne, France. Electronic address:

Carney complex is a rare familial multineoplastic syndrome predisposing to endocrine and nonendocrine tumors due to inactivating mutations of PRKAR1A, leading to perturbations of the cAMP‒protein kinase A signaling pathway. Skin lesions are the most common manifestation of Carney complex, including lentigines, blue nevi, and cutaneous myxomas in unusual locations such as oral and genital mucosa. Unlike endocrine disorders, the pathogenesis of skin lesions remains unexplained. Read More

Department of Maxillofacial Surgery, Medical University of Lodz, 113 S. Zeromski Street, 90-549 Lodz, Poland.

The differential diagnosis of benign nevi (BN), dysplastic nevi (DN), and melanomas (MM) represents a considerable clinical problem. These lesions are similar in clinical examination but have different prognoses and therapeutic management techniques. A texture analysis (TA) is a mathematical and statistical analysis of pixel patterns of a digital image. Read More

The Role of Reflectance Confocal Microscopy in the Evaluation of Pigmented Oral Lesions and Their Relationship With Histopathological Aspects.

Am J Dermatopathol 2022 May 3. Epub 2022 May 3.

Department of Stomatology, Dental School, University of Sao Paulo, Sao Paulo, Brazil; and.

Abstract: Oral pigmentations are a heterogeneous group and can be the result of physiological activity of oral mucosal melanocytes, secondary to exogenous causes, associated with systemic or local diseases, or due to proliferative activity of melanocytes. Their diagnosis is critical because these lesions can be markers of internal diseases or, in the case of melanocytic proliferative processes, they may represent a malignant neoplasm. In the past decade, the use of reflectance confocal microscopy, a noninvasive imaging tool, has aided the analysis of such lesions, but the establishment of firm criteria in their evaluation is still lacking.

Development of a targeted gene panel for the diagnosis of Gorlin syndrome.

Int J Oral Maxillofac Surg 2022 Apr 15. Epub 2022 Apr 15.

Department of Biochemistry, Tokyo Dental College, Chiyoda-ku, Tokyo, Japan. Electronic address:

Gorlin syndrome is a rare autosomal dominant disease caused by mutations in the PTCH1, PTCH2, and SUFU genes. Each symptom of the disease has a different time point of onset, which makes early diagnosis based solely on symptoms challenging. In this study, a gene panel was developed to overcome the challenges in the diagnosis of Gorlin syndrome and allow diagnosis using a single test. Read More

Blue Nevus of the Hard Palate: The Importance of a Careful Examination in an Emergency Setting.

Case Rep Dermatol Med 2022 15;2022:6329334. Epub 2022 Feb 15.

Stomatology Department, Centro Hospitalar Universitário de Lisboa Central, Lisbon, Portugal.

Oral common blue nevus is an asymptomatic, benign, rare, pigmented lesion and sometimes clinically indistinguishable from other pigmented lesions such as the cellular blue nevus or early-stage malignant melanoma. Since it shows clinical similarities with a malignant lesion and with cellular blue nevus that can itself suffer malignant transformation, the decisive diagnosis is crucial for adequate treatment, follow-up, and prognosis. Diagnosis confirmation is given by histological analysis, the reason why most oral pigmented lesions are excised. Read More

Melanoma Res 2022 02;32(1):59-62

Department of Dermatology, Ajou University School of Medicine.

Ponatinib, an oral third-generation tyrosine kinase inhibitor, is indicated for the treatment of imatinib-resistant leukemia. We experienced a case of ponatinib-induced eruptive nevi, and the biologic effects of ponatinib on melanocytes were investigated. Treatment with ponatinib significantly increased the proliferation of normal human melanocyte or melanoma cells through the upregulation of the extracellular signal-regulated kinase and protein kinase B signaling pathways.

Extracellular Matrix Remodeling by Fibroblast-MMP14 Regulates Melanoma Growth.

Int J Mol Sci 2021 Nov 12;22(22). Epub 2021 Nov 12.

Department of Dermatology and Venereology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50937 Cologne, Germany.

Maintaining a balanced state in remodeling the extracellular matrix is crucial for tissue homeostasis, and this process is altered during skin cancer progression. In melanoma, several proteolytic enzymes are expressed in a time and compartmentalized manner to support tumor progression by generating a permissive environment. One of these proteases is the matrix metalloproteinase 14 (MMP14). Read More

A Randomized Double-blind Placebo-controlled Trial of Oral Aspirin for Protection of Melanocytic Nevi Against UV-induced DNA Damage.

Cancer Prev Res (Phila) 2022 02 8;15(2):129-138. Epub 2021 Nov 8.

From the Huntsman Cancer Institute, University of Utah Health Sciences Center, Salt Lake City, Utah.

DNA damage plays a role in ultraviolet (UV)-induced melanoma. We previously showed that aspirin (ASA) can suppress prostaglandin-E (PGE) and protect melanocytes from UV-induced DNA damage in mice, and suggested that taking ASA before acute sun exposure may reduce melanoma risk. We conducted a prospective randomized placebo-controlled trial to determine if orally administered ASA could suppress PGE in plasma and nevi and protect nevi from UV-induced DNA damage. Read More

Department of Pediatric Endocrinology, Royal Manchester Children's Hospital, Manchester University NHS Foundation Trust, Oxford Road, Manchester M13 9WL, UK.

Cutaneous skeletal hypophosphatemia syndrome (CSHS) is a rare disorder caused by somatic mosaicism for the gain of function mutations . Affected patients have segmental epidermal nevi, dysplastic cortical bony lesions, and fibroblast growth factor-23 (FGF23)-mediated hypophosphatemic rickets. Herein, we describe a case of an Emirati girl with CSHS, whose hypophosphatemic rickets and osteomalcic pseudofractures and dysplastic bony lesions failed to recover due to poor adherence to treatment with oral phosphate supplements and alfacalcidol (conventional treatment).
