Malignant Acanthosis Nigricans: An Indicator of Internal Malignancy.

J Coll Physicians Surg Pak 2019 Sep;29(9):888-890

Department of Dermatology, Pak Emirates Military Hospital, Rawalpindi, Pakistan.

Acanthosis nigricans is a skin disease characterised by symmetric velvety hyperpigmented, verrucous plaques of the intertriginous surfaces of the axilla, neck, inframammary, and mucocutaneous regions. Malignant acanthosis nigricans is a paraneoplastic phenomenon most commonly associated with gastric adenocarcinoma. Tripe palms, florid cutaneous papillomatosis and oral involvement along with generalised acanthosis nigricans are the features which are highly suggestive of internal malignancy. Read More

Squamous cell carcinomas of the oral cavity and lips consistently have a high incidence (they constitute the fifth most common form of cancer in France) and carry a heavy prognosis, particularly if diagnosed late. According to different studies, between 10 and 80% of such carcinomas occur in a pre-existing or precancerous lesion. The World Health Organisation (WHO) recommends the use of two terms for such lesions: precursor lesions, i. Read More

Multifocal papillomavirus epithelial hyperplasia: successful treatment with CO2 laser therapy combined with interferon alpha-2b.

Int J Dermatol 2003 Sep;42(9):733-5

Department of Dermatology, Ankara University Medical Faculty, Ankara, Turkey.

Human papilloma virus (HPV) infections of the oral mucosa presents with various clinical and histopathologic features in relation with the causative HPV type and chronicity and the extent of the infection.1 The entity is known by several names based on histopathologic variations such as focal epithelial hyperplasia, oral florid papillomatosis, verrucous hyperplasia, oral florid verrucosis, and Ackerman's tumor. In recent years, the term multifocal papillomavirus epithelial hyperplasia (MPVEH) has been proposed to define the variant that usually occurs in childhood and is characterized by diffuse confluent papillomatous lesions in the oral mucosa.

Department of Veterinary Pathology, Institute of Comparative Medicine, Glasgow University, UK.

Tumorigenesis due to papillomavirus (PV) infection was first demonstrated in rabbits and cattle early last century. Despite the evidence obtained in animals, the role of viruses in human cancer was dismissed as irrelevant. It took a paradigm shift in the late 1970s for some viruses to be recognised as 'tumour viruses' in humans, and in 1995, more than 60 years after Rous's first demonstration of CRPV oncogenicity, WHO officially declared that 'HPV-16 and HPV-18 are carcinogenic to humans'.

Coexistence of acanthosis nigricans and the sign of Leser-Trélat in a patient with gastric adenocarcinoma: a case report and literature review.

J Am Acad Dermatol 2000 Feb;42(2 Pt 2):357-62

Department of Dermatology, King's College Hospital, London, United Kingdom.

The association of acanthosis nigricans (AN) with the sign of Leser-Trélat (LT) and gastric carcinoma is rare. Our patient was a 69-year-old man, who presented with hematemesis; a stage-IV poorly differentiated, diffuse-type, adenocarcinoma of the gastric antrum was diagnosed. The AN was striking, with florid cutaneous papillomatosis that also involved the mucous membranes of the mouth and eyelids, and keratoderma. Read More

Malignant acanthosis nigricans with florid papillary oral lesions.

Oral Surg Oral Med Oral Pathol Oral Radiol Endod 1996 Apr;81(4):445-9

Division of Oral Medicine and Radiology, Faculty of Dentistry, McGill University, Montreal, Québec, Canada.

Acanthosis nigricans is a distinctive skin disease of importance, because it has served as an external marker for a variety of systemic disorders including endocrinopathies, and malignant tumors of internal organs. It typically appears as hyperpigmented, roughened plaques of velvety consistency and infrequently as verruca-like papillations. The oral cavity and lips can be affected by florid papillary growths.

New Jersey Medical School, Newark 07103-2714.

The concept of verrucous carcinoma as a clinicopathologic variant of squamous cell carcinoma is worthy of recognition. It is known by a confusing array of names, such as Ackerman's tumor, Buschke-Loewenstein tumor, florid oral papillomatosis, epithelioma cuniculatum, carcinoma cuniculatum, and cutis papillomatosis carcinoides of Gottron. Its apparent clinical benignity may lead to lengthy periods of misdiagnosis, during which it is likely not to spread to distant lymph nodes, but rather to destroy a nose, mandible, or penis as it slowly but relentlessly extends into underlying tissue.

Head and Neck Surgical Group, Jackson, MS 39216.

Florid oral papillomatosis presents a picture of multiple squamous papillary lesions found in the oral pharynx. Multiple risk factors associated with the development of these lesions include possible association with papilloma virus, the use of tobacco products, and chronic inflammation or irritation such as that caused by poorly fitted dentures. The major risk factor of these benign squamous lesions is the dedifferentiation into a well-differentiated verrucous carcinoma. Read More

[Ambiguous keratosis. The situation of leukoplasia of the oral cavity].

Rev Stomatol Chir Maxillofac 1988 ;89(5):255-65

Service Central d'Anatomie Pathologique, Groupe Hospitalier Pitié-Salpêtrière, Paris.

The terminology used for white lesions of the oral cavity requires careful definition: the term keratosis is general, covering all lesions which by histological examination show evidence of keratin on the surface, regardless of other detectable lesions; the term leukoplasia is more restrictive, indicating (according to the WHO) white lesions not falling within the context of a known disease = lichen, lupus erythematosus, florid oral papillomatosis, chronic candidiasis, etc. This review chose the diagnostic difficulties of different varieties (planus, warty, erosive) of leukoplasia. In our experience the ambiguity of keratosis may be due to inadequate data from clinical examination and/or histological examination, to the combined existence in a given patient and at the same time of two white lesions of different nature, or to the successive existence at the same place of two lesions with a different clinical and/or histological diagnosis (raising the problem of transformation).
