Melanonychia corresponds to color patterns in the nail plate, ranging from brown to black. It is a diagnostic challenge due to the fact it has several differential diagnoses, including benign and malignant entities. There are no reports of pigmented fibroma of the nail matrix causing striata (or longitudinal) melanonychia. In light of this fact, the authors report a case of melanonychia striata...
Longitudinal melanonychia has been associated with a range of drugs, especially chemotherapeutic agents. We report 7 cases of melanonychia associated with the use of hydroxycarbamide for essential thrombocythemia. Of a patient population of 27, 7 (26%) developed melanonychia over a period of 2-7 years, and was not dose dependent. The high incidence of melanonychia in Chilean patients may be in ...
Longitudinal melanonychia presents in various conditions including neoplastic and reactive disorders. It is much more frequently seen in non-Caucasians than Caucasians. While most cases of nail apparatus melanoma start as longitudinal melanonychia, melanocytic nevi of the nail apparatus also typically accompany longitudinal melanonychia. Identifying the suspicious longitudinal melanonychia is t...
This statement, focused on melanonychia and nail plate dermoscopy, is intended to guide medical professionals working with melanonychia and to assist choosing appropriate management for melanonychia patients. The International Study Group on Melanonychia was founded in 2007 and currently has 30 members, including nail experts and dermatopathologists with special expertise in nails. The need for...
Melanonychia, or melanin-derived brown-to-black nail pigmentation, is a diagnostic challenge for clinicians. The most serious disease of the nail unit, melanoma, primarily presents with melanonychia. However, melanonychia most often occurs as a result of benign etiologies such as nail matrix melanocytic activation, nail matrix melanocytic hyperplasia, and nail invasion by melaninproducing patho...
Melanonychia commonly appears as a longitudinal band, starting from the matrix and extending to the tip of the nail plate. Less often it presents a transverse band or may inolve whole nail plate. Cutaneous side effects of hydroxyurea are described in 13% of patients including increased pigmentation, hyperkeratosis, skin atrophy, xerosis, lichenoid eruptions, palmar and plantar keratoderma, cuta...
Study Purposes. This study examined whether melanonychia was more prevalent in 1) HIV positive individuals compared to HIV negative persons, 2) HIV positives exposed to zidovudine and/or stavudine and 3) those with darker skin pigmentation. Procedures. 267 HIV positive and 273 HIV negative patients were examined for presence or absence of melanonychia and level of skin pigmentation using the Fi...
Melanonychia, or melanin-derived brown-to-black nail pigmentation, is a diagnostic challenge for clinicians. The most serious disease of the nail unit, melanoma, primarily presents with melanonychia. However, melanonychia most often occurs as a result of benign etiologies such as nail matrix melanocytic activation, nail matrix melanocytic hyperplasia, and nail invasion by melanin-producing path...
