Melanonychia striata: clarifying behind the Black Curtain. A review on clinical evaluation and management of the 21st century.

Int J Dermatol 2019 Apr 21. Epub 2019 Apr 21.

Departments of Pediatrics, Laboratory Medicine, and Pathology, The University of Alberta, Edmonton, Alberta, Canada.

Melanonychia striata is characterized by a tan, brown, or black longitudinal streak within the nail plate that runs from the proximal nail fold to the distal part of the nail plate. Melanonychia striata is due to increased activity of melanocytes or melanocytic hyperplasia in the nail matrix with subsequently increased melanin deposition in the nail plate. The most common cause of melanonychia striata associated with melanocytic activation is ethnic melanonychia which occurs in dark-skinned individuals. Read More

Laugier-Hunziker syndrome in a patient with rheumatoid arthritis.

Reumatologia 2019 28;57(1):63-65. Epub 2019 Feb 28.

Department of Dermatology and Venereology, Akdeniz University School of Medicine, Antalya, Turkey.

Laugier-Hunziker syndrome is a rare benign idiopathic condition characterized by acquired macular pigmentation of the lips and buccal mucosa, often accompanied by melanonychia. Although the etiopathogenesis is not fully known, tyrosine is thought to be responsible for the pathogenesis of enzyme hyperactivity in melanin biosynthesis. We present the case of a 66-year-old woman diagnosed with Laugier-Hunziker syndrome and rheumatoid arthritis. Read More

Use of Nail Dermoscopy in the Management of Melanonychia: Review.

Dermatol Pract Concept 2019 Jan 31;9(1):38-43. Epub 2019 Jan 31.

Department of Experimental, Diagnostic and Specialty Medicine-Division of_Dermatology, University of Bologna, Bologna, Italy.

The term melanonychia describes a black-brown-gray pigmentation of the nail plate that, in most cases, appears as a longitudinal band. Melanonychia can be observed at any age, affecting one digit or several digits, in both fingernails and toenails. Its causes can be difficult to differentiate clinically and depend on the number of bands and on their color, edge, and width. Read More

Retrospective single-center study evaluating clinical and dermoscopic features of longitudinal melanonychia, ABCDEF criteria, and risk of malignancy.

J Am Acad Dermatol 2019 May 11;80(5):1272-1283. Epub 2019 Feb 11.

Department of Dermatology, Weill Cornell Medicine, New York, New York. Electronic address:

Background: Longitudinal melanonychia (LM) is a common finding in clinical practice; however, it has a broad differential diagnosis, including subungual melanoma (SUM), which can be difficult to distinguish clinically from benign conditions.

Objective: To identify clinical and dermoscopic features that distinguish histopathologically diagnosed SUM from benign LM and to evaluate the validity of the ABCDEF criteria among patients on whom a biopsy was performed.

Methods: Retrospective cohort study of consecutive patients who underwent nail matrix biopsy for LM at a single center from January 2011 to November 2017. Read More

Transverse melanonychia in a child receiving chemotherapy.

Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania.

Transverse melanonychia is a rare finding often secondary to chemotherapy, orally ingested medications, or other iatrogenic interventions. A 19-month-old boy with hemophagocytic lymphohistiocytosis treated with biweekly etoposide and dexamethasone developed transverse bands of pigment in all toenail and fingernail units consistent with transverse melanonychia. We review the literature for reported cases of transverse melanonychia and summarize suspected etiologies. Read More

[Melanonychia].

Ugeskr Laeger 2018 Dec;180(50)

Melanonychia is seen, when melanin is incorporated in the nail, which gives a band of dark discolouration of the nail. Nail discolouration is a common cause for patients to seek medical attention, and it is often benign. Melanonychia can be seen due to melanocytic proliferation (ungual naevi), benign hyperplasia (lentigo) and hypermelanosis (infections, traumas). Read More

Postgraduate Department of Dermatology, STD & Leprosy, Government Medical College, Srinagar, University of Kashmir, Jammu & Kashmir, India.

Background: Nail disorders comprise approximately 10% of all dermatological conditions. Because diagnosis is not always possible by clinical means alone, additional diagnostic procedures may be required at times. Dermoscopy of nails (onychoscopy) has shown promising results in diagnosing various nail disorders and also avoids time-consuming investigations such as culture and biopsy. Read More

Isolated Nail Pigmentation Associated with Chikungunya: A Hitherto Unreported Manifestation.

Skin Appendage Disord 2018 Oct 3;4(4):312-314. Epub 2018 Jan 3.

Department of Dermatology, University College of Medical Sciences and Guru Teg Bahadur Hospital, University of Delhi, Delhi, India.

Chikungunya (CHK) fever is a re-emerging RNA viral infection caused by the bite of infected mosquitoes which presents with a multitude of mucocutaneous manifestations, including a characteristic morbilliform rash, centrofacial pigmentation, aphthae-like lesions, and vesiculobullous lesions sparing mucosae. The majority of these lesions resolve spontaneously and do not require specific therapy. With regular and cyclical outbreaks in many countries for many decades, it is obligatory for dermatologists to be aware of the different skin lesions in the wake of early diagnosis and the need for conservative management.

Faculty in Dermatopathology, Department of Dermatology, University of Puerto Rico Medical Sciences Campus, San Juan, Puerto Rico.

Pigmented lesions of the nail unit are commonly encountered in the clinical setting. Yet, they often present a unique challenge to clinicians because of a broad differential diagnosis or unfamiliarity with clinical and histopathologic features. A wide variety of causes exist ranging from benign lesions such as subungual hemorrhage to malignant lesions such as subungual melanoma. Read More

Mystery behind labial and oral melanotic macules: Clinical, dermoscopic and pathological aspects of Laugier-Hunziker syndrome.

World J Clin Cases 2018 Sep;6(10):322-334

Department of Oral Medicine, Nanjing Stomatological Hospital, Medical School of Nanjing University, Nanjing 210008, Jiangsu Province, China.

Labial and oral melanotic macules are commonly encountered in a broad range of conditions ranging from physiologic pigmentation to a sign of an underlying life-threatening disease. Although Laugier-Hunziker syndrome (LHS) shares some features of labial and oral pigmentation with a variety of conditions, it is a benign and acquired condition, frequently associated with longitudinal melanonychia. Herein, the demographic, clinical, dermoscopic, and pathological aspects of LHS were reviewed comprehensively. Read More

Assessment of a Predictive Scoring Model for Dermoscopy of Subungual Melanoma In Situ.

JAMA Dermatol 2018 Aug;154(8):890-896

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

Importance: Subungual melanoma in situ (SMIS) is a malignant neoplasm that requires early diagnosis and complete surgical excision; however, little is known about the usefulness of the detailed dermoscopic features of longitudinal melanonychia (LM) to predict the diagnosis of SMIS.

Objectives: To investigate the characteristic dermoscopic findings of SMIS and to establish a predictive scoring model for the diagnosis of SMIS in patients with adult-onset LM affecting a single digit.

Design, Setting, And Participants: A cohort study of 19 patients with biopsy-proven SMIS and 26 patients with benign LM diagnosed in a tertiary referral hospital in Seoul, South Korea, from September 1, 2013, to July 31, 2017. Read More

Longitudinal Melanonychia Biopsy: What Not to Do.

Dermatologists are the first-line diagnosticians for these pigmented lesions of the nail unit, however, for different reasons, some are reluctant to perform a nail biopsy. This case demonstrates how a poor biopsy technique resulted in a misdiagnosis in a patient with melanoma in situ. Read More
