Acanthosis nigricans (AN) is characterized by velvety, hyperpigmented, verrucous, symmetric and occasionally pruritic plaques along with papillomatous lesions which have a special predilection for neck, axillae, groin, umbilicu and mucosal regions. Rarely, it presents as a paraneoplastic syndrome and prompts a thorough search for an internal malignancy. We present here a case of malignant acant...

A case is described of a three-day-old female with salt wasting type of 21-hydroxylase deficient congenital adrenal hyperplasia who presented with acanthosis nigricans of both axillae. Following corticosteroid and mineralocorticoid therapy for disease, the acanthosis nigricans resolved. It is believed that this is the first reported case of acanthosis nigricans occurring in association with con...

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 res...

acanthosis nigricans (an), tripe palm (tp) and sign of lesser trelat (lt) are rare dermatoses which are often seen with malignant conditions. acanthosis nigricans occurs both on the skin and mucus membranes as velvety hyper pigmented lesions in the flexors and around the neck, or papillomatous and verrucous lesions on the lips and buccal mucosa. these para neoplastic dermatoses are generally li...

Acanthosis nigricans is characterized by the triad of papillomatosis, keratin hyperplasia and pigmentation in the skin. It develops in the nape of the neck, axilla and external genitalia in many cases. It was reported, however, that papilloma and hyperplastic epithelial lesions were observed also in the lip, oral cavity, esophagus and anus in some cases (Ueno, 1962). A patient with advanced gas...

Objectives: Acanthosis nigricans refers to the velvety, black hyperpigmentation seen in the flexures. It is a cutaneous marker for insulin resistance (IR), some metabolic disorders and rarely malignancy. When secondary to IR, it is asymptomatic, except for the hyperpigmentation. The neck is the most accessible and easiest to grade. Our aim was to identify the predictive value of the grades of a...

IMPORTANCE Crouzon syndrome with acanthosis nigricans is a distinct disorder caused by a mutation in the FGFR3 gene, featuring craniosynostosis, characteristic facial features, and atypical and extensive acanthosis nigricans. Other cutaneous findings have not been thoroughly described. OBSERVATIONS We report 6 cases and summarize the existing literature with regard to the cutaneous manifestat...

Malignant acanthosis nigricans is a cutaneous eruption characterized by symmetric hyperpigmented hyperkeratosis, dermal papillomatosis, and mucosal involvement associated with internal malignancies. Tripe palms refers to a characteristic velvety thickening of the palms, with exaggeration of normal skin markings. We present the second case of ovarian cancer in association with two coexisting par...

Some skin lesions may accompany malignancies. Acanthosis nigricans, one such lesion, is a paraneoplastic dermatosis characterized by hyperpigmented and velvety verrucose plaques observed as symetric eruptions. With this report, we aim to present a rare case of concomitant lung cancer and acanthosis nigricans. Malignant acanthosis nigricans is most commonly associated with intra-abdominal malign...
