Anogenital giant seborrheic keratosis.

G Ital Dermatol Venereol 2017 Aug 21;152(4):383-386. Epub 2015 Jan 21.

Georg Schmorl Institute of Pathology, Dresden-Friedrichstadt Academic Teaching Hospital, Dresden, Germany.

Seborrheic keratosis (SK) are very common benign epidermal tumors. Giant seborrheic keratosis (GSK) is a rare variant with clinical characteristics, which leads very often to misdiagnosis. A genital site of SK is very unusual clinical manifestation and although the cause is still unknown, current literature data point to a possible pathogenetic role of chronic friction and HPV infection.

Multifocal cutaneous melanoacanthoma with ulceration: a case report with review of literature.

Indian J Dermatol Venereol Leprol 2011 Nov-Dec;77(6):699-702

Department of Dermatology, Maulana Azad Medical College and Lok Nayak Hospital, New Delhi, India.

We report a case of a 58-year-old female patient who presented with multiple, asymptomatic, slowly-growing, raised pigmented lesions all over her body for the past 10 years with ulceration in one of the lesions on the trunk for the past five months. Histopathology of the lesion revealed features consistent with melanoacanthoma. Here, we report the first case of cutaneous melanoacanthoma presenting with an ulcerated plaque and the third case of cutaneous melanoacanthoma with multiple lesions. Read More

A Case of Melanoacanthoma: Immunohistochemical Staining Using VECTOR® NovaRED™ to Distinguish Melanocytes from the Cutaneous Pigment.

Ann Dermatol 2008 Mar 31;20(1):18-21. Epub 2008 Mar 31.

Department of Dermatology, College of Medicine, Korea University, Seoul, Korea.

Melanoacanthoma is a rare benign mixed tumor of both keratinocytes and melanocytes. Although some authors said that it is a rare variant of seborrheic keratosis, it has clinical and histological features distinct from seborrheic keratosis. It has large dendritic melanin-laden melanocytes throughout all levels of epidermis showing a disruption of melanin transfer from the melanocytes to neighboring keratinocytes. Read More

Oral melanoacanthoma and oral melanotic macule: a report of 8 cases, review of the literature, and immunohistochemical analysis.

Med Oral Patol Oral Cir Bucal 2007 Sep 1;12(5):E374-9. Epub 2007 Sep 1.

Departamento de Patología y Medicina Oral, Centro Clínico de Cabeza y Cuello, Guatemala.

Oral melanoacanthoma (MA) is a rare, benign pigmented lesion, similar to cutaneous MA, characterized by hyperplasia of spinous keratinocytes and dendritic melanocytes. The pathogenesis of oral MA remains uncertain, although its clinical behavior is suggestive of a reactive origin. The most common intraoral sites are the buccal mucosa, lip, palate and gingiva.

Oral melanoacanthosis (melanoachantoma): report of a case and review of the literature.

Med Oral Patol Oral Cir Bucal 2005 Jan-Feb;10(1):11-2; 9-11

Centro de Medicina Oral de Guatemala, Ciudad de Guatemala, Guatemala.

Oral melanoacanthosis (MA) is a rare pigmented mucosal lesion that is considered the counterpart of cutaneous melanoacanthoma. Microscopically the superficial epithelium shows mild to moderate acanthosis, spongiosis and prominent dendritic melanin producing melanocytes, which are present throughout the spinous keratinocytes. Reported cases show predilection for black females and the most common locations in decreasing frequency are buccal mucosa, lip, palate and gingiva. Read More

Oral melanoacanthoma: a report of 10 cases, review of the literature, and immunohistochemical analysis for HMB-45 reactivity.

Am J Dermatopathol 2003 Feb;25(1):12-5

Department of Oral and Maxillofacial Pathology, Medicine and Surgery, Temple University School of Dentistry, Philadelphia, Pennsylvania 19140-5096, USA.

Oral melanoacanthoma (MA) is rare reactive mucosal lesion that, like cutaneous MA, demonstrates hyperplasia of spinous keratinocytes and melanocytes. Unlike MA of the skin, oral MA is unrelated to seborrheic keratosis. This series adds 10 cases to the limited number of previous reports of oral MA. Read More

Melanoacanthosis (melanoacanthoma) of the oral mucosa.

Authors:
C E Tomich S L Zunt

J Dermatol Surg Oncol 1990 Mar;16(3):231-6

Department of Oral Pathology, Indiana University School of Dentistry, Indianapolis.

A pigmented lesion of the oral mucosa that bears histologic resemblance to the cutaneous melanoacanthoma is discussed. A study of 22 cases, including 4 in the current series, shows that the intraoral lesion occurs most commonly in adult black women on the buccal mucosa and lip. The lesion is known to regress.

Mucosal melanosis.

Authors:
J C Maize

Dermatol Clin 1988 Apr;6(2):283-93

Medical University of South Carolina, Charleston.

The labial melanotic macule has an increased number of dendritic melanocytes along the basal layer. Numerous counterparts of the labial melanotic macule occur on the other mucosal and cutaneous surfaces. Most melanoacanthomas of the lip show a similar number of melanocytes along the junctional zone. Read More

Melanotic macules and melanoacanthomas of the lip. A comparative study with census of the basal melanocyte population.

Am J Dermatopathol 1987 Oct;9(5):438-44

Department of Pathology, Milton S. Hershey Medical Center, Hershey, Pennsylvania.

Fifteen labial melanotic macules and three melanoacanthomas of the lip were studied with particular regard to their distinguishing histopathological features including a quantitative study of the basal melanocyte population. Both of these entities show an increased population of melanocytes arranged as single units along the junctional zone. These conditions differ from each other primarily by the presence of intraepithelial melanocytes in melanoacanthoma. Read More
