“…Clinically, it presents as asymptomatic, asymmetrical, black-to-brown-colored macules, isolated or in clusters, with an uninterrupted normal skin surface [3]. The pathogenesis can be explained by damage of the papillary dermal blood vessels due to shearing forces related to sports activity, climbing, or any kind of repetitive microtrauma that eventually leads to the leakage of blood from the dermis to the epidermis [3,8]. In our case, the lesions had an unusual location on the forefoot just below the metatarsals, and there was no association with sports activity.…”

Talon noir is an asymptomatic, self-limiting, dermatological condition that is most commonly seen in young athletes and mountain climbers. Histologically, the characteristic findings are intraepidermal hemorrhage and fluid collection due to shearing forces. Here, we report an interesting case in an elderly female, which mimicked acral melanoma clinically and alerted us to do a biopsy for confirmation.

“…Examples include talon noir and subungual hemorrhage. 34,35 In addition, the use of nail polish has been considered in the differential diagnosis of subungual hemorrhage and nail plate pigmentation. Although the histopathology of nail polish can exhibit hyperpigmentation with larger granules similar to silver granules, nail polish is located exclusively on the dorsal aspect of the nail plate.…”

A clinical mimicker of melanoma with distinctive histopathology: Topical silver nitrate exposure

Exposure to silver-containing compounds can result in reversible discoloration of the skin, presenting as an irregular brown or black macule, which can have a clinical appearance similar to melanoma. Both the clinical scenario and the histopathology are unique. Silver nitrate darkens with exposure to light, and the area can appear to change over time. On microscopic examination, there are coarse pigmented granules dispersed throughout the corneal layer, and largely absent from the remainder of the epidermis-although the precise location may depend on the duration of topical exposure. While argyria, its irreversible counterpart, has been well-characterized, only a single source has previously reported the histopathology of transient topical silver nitrate exposure. We present two cases, review the clinical and histopathologic differentials, and detail the distinctive histopathology that enables a diagnosis to be suggested in this clinical mimicker of melanoma.

“…In 15 cases there were 9 male patients and 6 female patients, the male to female ratio was 1.5:1, which according to the related domestic records [9] . But some studies suggested that this ratio was different in different race or countries [10] , for example, in Gavriel's study, there are more female patients than male patients, that may because of different races or social and environment factors in different countries. In this study, according to analyze the medical records of malignant melanoma of head and neck, the result shows that gender has no effect on the prognosis of Malignant Melanoma(P 0.05) but in the research of Davar [12] it suggested that the prognosis of female patients were better than male patients [12] .…”

Objective: We analyze the pathogenesis, clinical characteristics, diagnosis, treatment and histological feature of Malignant Melanoma in the head and neck. To improve the understanding and help the early diagnosis and treatment of the disease. As a result, improve the treatment and prognosis of Malignant Melanoma in head and neck.Method: We collect 15 cases of Malignant Melanoma in the head and neck region treated in the Department of Oral and Maxillofacial Surgery in Shengjing Hospital of China Medical University. All data were obtained from patient’s medical records which including the pathogenesis, clinical and histological features, diagnosis, treatment and prognosis.Result: This study included 15 cases, there are 9 male and 6 female patients. The average age is 62.9 years lid, the oldest one is 75 years old and the youngest one is 40 years old. 2 cases occurred in the lip, 2 cases occurred in the tongue, 2 cases occurred in the submandibular area, 1 cases occurred in the parotid gland, 1 case occurred in the neck, other 7 cases occurred in the gingiva. The cases occurred in the lip, gingiva, tongue, parotid gland and submandibular area are primary tumor, cases occurred in neck were metastasis. 6 cases were treated by surgical excision. 1 cases occurred in gingiva was treated by surgical excision combine with chemotherapy. 5 years followed up has been taken. 10 cases were dead because of recurrence and metastasis in 5 years after the operation. 5 patients do not have a relapse and still alive.Conclusion: Malignant Melanoma in the head and neck are mostly affected the old people. In this study gingiva is the most commonly primary site, neck is the most commonly transferring site. The diagnosis of malignant Melanoma is mainly relying on the clinical manifestation and pathological examination. Histopathological examination is considered the golden standard for diagnosis. Surgical excision combined with chemotherapy is the main treatment modality for Malignant Melanoma. Cryotherapy and immunotherapy also have been used in the treatment. The prognosis of Malignant Melanoma is poor. So early detection and early treatment is important in the treatment.
