We discuss a 48-year old, who presented with upper epigastrium pain associated with early satiety and significant weight loss. Physical examination revealed a thickening and darkening of skins around the skin folds, scalp, back and front of abdomen. A diagnosis of gastro-esophageal junction adenocarcinoma was confirmed by oesophagogastroduodenoscopy (OGDS) and biopsy. The biopsy of the skin lesion revealed a diagnosis of acanthosis nigricans, He underwent a total gastrectomy followed by adjuvant chemo-radiotherapy...

Paraneoplastic itch occurs as the result of a systemic reaction to an underlying malignancy. Paraneoplastic itch is most commonly associated with lymphoproliferative malignancies and solid tumors that result in cholestasis. Paraneoplastic itch may occur in the absence of a primary rash or in association with dermatologic conditions such as erythroderma, acanthosis nigricans, dermatomyositis, Grover's disease, and eruptive seborrheic keratosis. Treatment of paraneoplastic itch is centered on targeting the underlying malignancy responsible for the systemic reaction...

A 55-year-old man presented with oral mucosal ulcers, blackening of both hands, and hyperpigmentation on axillary, anal, and inguinal regions for the last 3 months, which were all progressive. The patient was referred to the oncology department with the diagnosis of acanthosis nigricans for investigation of an underlying malignancy. He was a smoker. A computed tomography scan of thorax revealed enlarged mediastinal lymphadenopathies and a lesion on the left upper lobe. Fine-needle aspiration biopsy of the mediastinal lesion was consistent with squamous cell carcinoma, and biopsies of the skin and oral mucosal lesion also further confirmed the diagnosis of acanthosis nigricans...

Skin lesions are frequently encountered in clinical practice which can be a presentation of systemic diseases not excluding an occult malignancy. Commonly reported paraneoplastic dermatologic manifestations include acanthosis nigricans, dermatomyositis, erythroderma, hypertrophic osteoarthropathy, Sweet syndrome, and paraneoplastic pemphigus (PNP). PNP is a rare autoimmune mucocutaneous disease characterized by severe stomatitis, polymorphic skin eruptions, and associated underlying neoplasms most commonly non-Hodgkin's lymphoma, chronic lymphocytic leukemia, and Castleman disease...

Acanthosis nigricans (AN), an entity recognized since the 19th century, is a dermatopathy associated with insulin-resistant conditions, endocrinopathies, drugs, chromosome abnormalities and neoplasia. The latter, also known as malignant AN, is mostly related to abdominal neoplasms. Malignant AN occurs frequently among elderly patients. In these cases, the onset is subtle, and spreading involves the flexural regions of the body, particularly the axillae, palms, soles, and mucosa. Gastric adenocarcinoma is the most frequent associated neoplasia, but many others have been reported...

Cindy England Owen
Skin findings can serve as a clue to internal disease. In this article, cutaneous manifestations of underlying lung malignancy are reviewed. Paraneoplastic dermatoses are rare, but when recognized early, can lead to early diagnosis of an underlying neoplasm. Malignancy-associated dermatoses comprise a broad group of hyperproliferative and inflammatory disorders, disorders caused by tumor production of hormonal or metabolic factors, autoimmune connective tissue diseases, among others. In this review, paraneoplastic syndromes associated with lung malignancy are discussed, including ectopic ACTH syndrome, bronchial carcinoid variant syndrome, secondary hypertrophic osteoarthropathy/digital clubbing, erythema gyratum repens, malignant acanthosis nigricans, sign of Leser-Trélat, tripe palms, hypertrichosis lanuginosa, acrokeratosis paraneoplastica, and dermatomyositis...

The skin is often the herald of an underlying systemic illness, and gastrointestinal malignancies can present in numerous ways in the skin. Paraneoplastic phenomenon, such as acanthosis nigricans and tripe palm, may be the first indicator of a gastrointestinal malignancy. In addition, gastrointestinal cancers can metastasize to the skin, as described in the well-known Sister Mary Joseph's nodule. Inflammatory systemic conditions such as dermatomyositis and multicentric reticulohistiocytosis can be associated with underlying malignancy...

Metformin though primarily an antidiabetic drug, has found to play an important role in a number of cutaneous disorders. Because of its role in improving hyperinsulinemia, it has proven beneficial in hormonal acne, hidradenitis suppurativa (HS) and acanthosis nigricans. Its antiandrogenic properties further serve as an add-on to the conventional management of hirsutism associated with polycystic ovarian syndrome. Very recently, systemic usage of metformin for psoriasis and cutaneous malignancies has shown promising results...

Extramammary Paget disease (EMPD) is a rare malignant neoplasm of apocrine sweat glands that is morphologically and histologically identical to Paget disease of the breast. The primary lesion is usually a solitary, well-demarcated, erythematous, scaly plaque that may contain crust, erosions, or ulcerations. The vulva is the most common site, but any area containing apocrine sweat glands may be involved. We present a case of triple extramammary Paget disease of the groin and bilateral axillae in a diabetic patient whose axillary lesions appeared consistent with acanthosis nigricans...

Dermatology is greatly understudied in the American Indian/Alaska Native (AIAN) population. This topic deserves attention in light of the changing demographics of the United States and the healthcare disparities faced by AIAN, including access to dermatologic care. In this review, we discuss disorders that are more prevalent or otherwise important in the AIAN population, such as cutaneous malignancies, photodermatoses, acanthosis nigricans, connective tissue disorders, cutaneous infections, hypertrophic scar formation, and Heck's disease...

Acanthosis nigricans maligna (ANM) is a paraneoplastic phenomenon most commonly associated with visceral adenocarcinoma, in particular, gastric adenocarcinoma. Clinically, AMN is characterized by rapidly progressive symmetrical skin thickening and hyperpigmentation of the intertriginous areas with peripheral acrochorda. The diagnosis is made by a detailed medical work-up for occult malignancies with particular emphasis on endocrinological diseases. We report a 67-year-old man that presented clinically with acanthosis nigricans, in which a subsequent diagnosis of mycosis fungoides was made...

Acanthosis nigricans (AN) is a dermatosis characterized by velvety, papillomatous, brownish-black, hyperkeratotic plaques, typically on the intertriginous surfaces and neck. The majority (80%) of AN occurs idiopathically or in benign conditions such as endocrinopathies like diabetes mellitus, polycystic ovary syndrome; metabolic syndrome and/or heritable disease. Malignancy-associated AN is rare. AN may rarely be associated with autoimmune diseases including systemic lupus erythematosus, due to antibodies to the insulin receptor, so-called type B insulin resistance...

Acanthosis nigricans (AN) is a mucocutaneous disorder that is characterized by focal or diffuse hyperkeratotic, surfaces, which are symmetrically distributed hyperpigmented lesions of the skin. It rarely affects mucosal surfaces like oral cavities. Although it is commonly seen in adolescents, AN is also increasingly seen in children who are obese. Recent studies have found that AN can be a cutaneous indicator of insulin resistance and malignancy. Acanthosis nigricans has been associated with type 2 diabetes mellitus, obesity, endocrinopathies, drugs, and malignancies...

FGFR3 mutations cause wide spectrum of disorders ranging from skeletal dysplasias (hypochondroplasia, achondroplasia, and thanatophoric dysplasia), benign skin tumors (epidermal nevi, seborrhaeic keratosis, and acanthosis nigricans), and epithelial malignancies (multiple myeloma and prostate and bladder carcinoma). Hypochondroplasia is the most common type of short-limb dwarfism in children resulting from fibroblast growth factor receptor 3 (FGFR3) mutation. Acanthosis nigricans might be seen in severe skeletal dysplasia, including thanatophoric dysplasia and SADDAN syndrome, without a biochemical evidence of hyperinsulinemia...

BACKGROUND: Acanthosis nigricans is characterized by hyperpigmentation and hyperkeratosis of the skin or mucous membranes. Its malignant form is associated with internal neoplasms, especially gastric adenocarcinoma (55-61%). Coexistence with prostate cancer is uncommon. In the paraneoplastic type of this dermatosis, the skin and mucous lesions are characteristically of more sudden onset and more severe than those in the benign form. The efficacy of various treatment strategies remains disappointing...

The skin may exhibit the first clinical evidence of a systemic disease and may provide the first clues to a diagnosis in malignancies. Erythroderma is defined as generalized redness and scaling and it is a clinical manifestation of a variety of underlying diseases including, rarely, solid tumors. Breast cancer is associated with a variety of skin paraneoplastic manifestations like acanthosis nigricans, erythromelalgia, thrombotic thrombocytopenic purpura, acrokeratosis paraneoplastica, dermatomyositis, systemic sclerosis, and scleroderma...
