Int J Dermatol 2021; 60:1376-1384. [PMID: 34018611 DOI: 10.1111/ijd.15630] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 03/26/2021] [Accepted: 04/07/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Partial unilateral lentiginosis (PUL) is a rare acquired circumscribed hyperpigmentation characterized by multiple simple lentigines involving half of the body. Since the previous studies of PUL were mostly based on case reports and the current literature lacks well-designed retrospective studies that involve a large number of cases, PUL is not a well-defined entity, and differential diagnosis with nevus spilus is still difficult. This study aims to evaluate clinical and histopathological characteristics and treatment outcomes of PUL on head and neck area of Koreans. METHODS Thirty-two patients with PUL on head and neck area were diagnosed clinicohistopathologically at the Asan Medical Center from 2004 to 2017. Their medical records, photographs, and biopsy specimens were reviewed, and immunohistochemical staining for protein kinase C (PKC)-βΙΙ was evaluated for melanogenic activity. RESULTS Four patients (12.5%) of PUL had congenital lesions, and 24 (75.0%) had age of onset younger than 10 years. Confluency of lentiginous lesions (100%) and mild to moderate background interlesional hyperpigmentation (90.6%) were observed. The lentiginous lesions showed increased melanocytes, melanophages, basal melanins, lentiginous hyperplasia, and perivascular inflammatory cells compared with background interlesional hyperpigmentation, and PKC-βΙΙ was focally positive in 7 of 12 stained PUL lesions. Among the 16 patients who received laser treatments, 10 (62.5%) showed more than 50% of improvement. CONCLUSIONS The findings of this study will allow for improved diagnosis of PUL and understanding of its features, which may facilitate proper management in the future.

Abstract
Nevus spilus is a melanocytic cutaneous lesion consisting of a light brown
background macule with numerous superimposed darker maculopapular speckles.
Melanoma arising from a nevus spilus is rare, with less than 40 cases reported
to date. The absolute risk for malignant transformation is not well defined,
lacking a standardized management approach. We report a new case of melanoma
arising from nevus spilus, with the additional peculiarity of multifocality. We
offer our recommendations for the management of the condition.

Abstract
Nevus spilus, also known as speckled lentiginous nevus, is a nevoid disorder characterized by hyperpigmented macules or papules scattered over a background of tan pigmentation. Although nevus spilus is mainly of cosmetic concern, malignant melanoma may rarely develop in the lesions. Although classically not mentioned as a hairy nevus, a few reports in literature mention overlying hypertrichosis in lesions of nevus spilus. We hereby report four cases of nevus spilus without malignant change with overlying terminal hairs that arose mainly from the background pigmented area.

Abstract
Agminated Spitz nevus arising on a background of nevus spilus (NS) is a rare condition. We report here a further case in a child that is original because it is induced by chemotherapy. A 3-year-old boy presented 3 months after the onset of a chemotherapy for a vesico-prostatic rhabdomyosarcoma, multiple pigmented papulo-nodules located on the face, neck, chest wall, and the higher back. These lesions have arose on a pre-existent large congenital histologically confirmed nevus spilus extending along the face, neck, the left shoulder and the left chest wall. Histological examination of three excised nodules led to the diagnosis of Spitz nevus. Our patient may have a high risk for melanoma since he has many criteria predisposing to this risk. Some of these criteria are related to NS but we should also take into account the chemotherapy induction and the high number of Spitz nevi.

Abstract
Background: Nevus spilus is characterized by a pigmented patch with scattered flat or maculopapular speckles. Nevus spilus was first described by Burkley in 1842. Since then, this lesion has been widely debated in the literature, particularly for the possible occurrence of melanoma within the lesion. Objective: We describe the case of a 65-year-old female presenting with a nodular achromic melanoma that occurred within a nevus spilus on the left thigh. Conclusion: Our observation is consistent with the idea that this entity in some circumstances may have the ability to evolve into a malignant melanoma.

Abstract
BACKGROUND Diagnosis of naevus lesions may be complex where they contain little or no pigmentation. Naevus spilus (or naevus on naevus) is, generally, readily identified by the difference in pigmentation between overlying and underlying naevi and healthy skin. Malignant transformation of naevus spilus is rare. We report two cases of melanoma in which surgical procedures revealed underlying melanocyte lesions, diagnosed at histology but undetectable on clinical examination. PATIENTS AND METHODS Two patients were operated for melanoma in which surgery, at a site remote from the melanoma, suggested incomplete relapse despite the fact that previous clinical examination had indicated healthy skin. A diagnosis was made of melanoma in invisible naevus spilus. DISCUSSION Diagnosis of melanoma in invisible naevus spilus may be suspected where several naevi are found together in a specific area. The main problem is the therapeutic stance to be adopted since complete excision of the underlying naevi is difficult in practice. Wood's light examination may be helpful.

Abstract
Neurofibromatosis type 1 is an autosomal dominant disease and is considered one of the most commonly inherited diseases in humans. Malignant melanoma has been reported in up to 5% of patients with neurofibromatosis type 1. We report a young Saudi boy with neurofibromatosis type 1 who developed fatal metastatic malignant melanoma arising from giant melanocytic nevi within speckled lentiginous nevus (SLN).
