Oral melanoacanthoma: Clinicopathological and immunohistochemical features of a case series and a scoping review.
J Oral Pathol Med
November 2023
Department of Oral Pathology and Surgery, School of Dentistry, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil.
Article Synopsis
- * Histological findings included epithelial acanthosis and melanin incontinence, with TRP2-positive melanocytes found in all cases, while T-lymphocytes predominantly outnumbered B-lymphocytes.
- * A broader scoping review identified 85 additional cases, predominantly in females and black-skinned individuals, suggesting that oral melanoacanthoma primarily affects the buccal mucosa and may arise from specific immune cell involvement.
Habitual khat chewing and oral melanoacanthoma: A case report.
World J Clin Cases
January 2023
Postgraduate, College of Dentistry, Princess Nourah Bint Abdulrahman University, Riyadh 11671, Saudi Arabia.
Article Synopsis
- Habitual khat chewing can lead to various changes in oral tissues, including a rare condition called oral melanoacanthoma, which is a benign pigmentation in the mouth.
- A case study of a 26-year-old male showcased this link, as his regular khat use triggered the development of oral melanoacanthoma, confirmed through medical history and biopsy.
- The study emphasizes that chronic khat chewing is a significant extrinsic factor contributing to oral tissue changes, highlighting the need for awareness of its potential health risks.
Melanoacanthoma, Plasma Cell Cheilitis and Langerhans Cell Hyperplasia on the Lower Lip: An Unusual Association and Immunohistochemical Analysis.
Indian J Dermatol
January 2022
Oral Pathology, Department of Stomatology, Public Oral Health, and Forensic Dentistry, Ribeirão Preto Dental School (FORP/USP), University of São Paulo, Ribeirão Preto, São Paulo, Brazil.
Article Synopsis
- Oral melanoacanthoma is a rare lesion with increased keratinocyte growth and melanin-rich dendritic melanocytes, while plasma cell cheilitis (PCC) is an inflammatory condition characterized by a dense infiltration of plasma cells, mainly affecting the lower lip.
- The study presents a unique case of a 59-year-old male with an unusual combination of melanoacanthoma, PCC, and Langerhans cell hyperplasia (LCHyp) occurring on the lower lip, showcasing the varied nature of these lesions.
- Histological analysis utilized stains like Fontana-Masson and HMB-45 to identify dendritic melanocytes, along with markers like MUM1/IRF4 to show plasma
