Abstract
Melanocytic nevi are frequently accompanied by inflammatory cells of different types, in varied amounts and distributed in different patterns. In the current report, we review the knowledge on inflammation seen in different types of melanocytic nevi. As an additional contribution, we studied the lymphocytic inflammatory component of Duperrat nevus, as well as the cytotoxic component of Sutton nevus, two contributions that we have not found in the literature. We conclude that: (a) Duperrat nevus has a mixed inflammatory reaction that includes histiocytes, foreign-body multinucleated giant cells, polymorphonuclears, lymphocytes (predominantly CD4+) and plasma cells (commonly abundant); (b) common melanocytic nevi with reactive inflammatory infiltrate usually show a CD4+ predominant population; (c) Meyerson nevus commonly shows an inflammatory infiltrate mainly made up of CD4+ T-cells; (d) Sutton nevus with halo phenomenon is accompanied by a dense inflammatory infiltrate with lymphocytes in a CD4:CD8 ratio varying from 1:1 to 1:3 and in which most of the CD8+ T-cells do not express cytotoxic markers; (e) Wiesner nevus commonly shows a spare lymphocytic infiltrate but the nature of the infiltrate has not yet been investigated.

Abstract
Intrascrotal extratesticular neurofibromas (IEN) often originate from genitofemoral nerve (GFN) and present as a paratesticular mass. Synchronous presence of IEN and undescended testis has not been reported previously. A 12-year-old boy with neurocutaneous syndrome and congenital giant melanocytic nevi along with IEN and ipsilateral undescended testis is presented, to discuss the underlying pathophysiology of failed testicular descent in the presence of IEN.

Abstract
Congenital melanocytic nevi (CMN) are evident in 1% to 6% of neonates. In some studies, nevi with clinical, dermatoscopic, and histologic features identical to CMN have had a prevalence of more than 15% in older children and adults, possibly reflecting the "tardive" appearance of nevi programmed from birth. There is ongoing debate about the magnitude of the risk of melanoma and other complications associated with CMN of various sizes and the best approach to management of these lesions. We review the natural history of CMN, including proliferative nodules and erosions during infancy, neurotization, and spontaneous regression, and features of variants such as speckled lentiginous and congenital blue nevi. The risk of melanoma arising within small-sized (<1.5 cm) and medium-sized CMN is low (likely <1% over a lifetime) and virtually nonexistent before puberty. Recent data suggest that melanoma (cutaneous or extracutaneous) develops in approximately 5% of patients with a large (>20 cm) CMN, with about half of this risk in the first few years of life. Melanoma and neurocutaneous melanocytosis (NCM) are most likely in patients with CMN that have a final size of >40 cm in diameter, numerous satellite nevi, and a truncal location. One-third of individuals with NCM have multiple medium-sized (but no large) CMN. In patients at risk for NCM, a screening gadolinium-enhanced magnetic resonance imaging, preferably before age 6 months, and longitudinal neurologic assessment are recommended. Management of CMN depends on such factors as the ease of monitoring (more difficult for large, dark, thick nevi) and cosmetic and psychologic benefits of excision or other procedures. CMN require lifelong follow-up. Periodic total body skin examinations are necessary for all patients with large CMN, even when complete resection (often impossible) has been attempted.

Abstract
The risk to develop melanoma from small or medium size congenital naevus remain controversial. The main goal of the present study was to determine the interest of three immunohistochemical markers (Ki67, HMB45 and p53) in predicting malignant transformation of these congenital naevi and to see if a specific immunohistochemical profile of such transformed naevi can be identified. The markers (Ki67, HMB45 and p53) have been used retrospectively on sections of small or medium size congenital naevi (group NC, n = 15), of melanoma developed on small or medium size congenital naevi (group MNC, n = 15) and of melanoma developed on acquired naevi (group MNA, n = 15). The labelled cells have been counted in different cutaneous layers: junction, superficial dermal layer and deep dermal layer. No reactivity was observed for the three markers in group NC. The percentage of labelled cells was significantly different for the three markers between the group NC and the groups MNC and MNA. There was no difference between the groups MNC and MNA. In the groups MNC and MNA, a gradient in the percentage of labelled cells was observed between superficial and deep layers. These three markers do not differentiate melanoma developed from congenital naevi of small or medium size and melanoma developed from acquired naevi. Moreover, the results suggest that these three markers are useless in predicting the risk of malignant transformation of small or medium size congenital naevi.

Abstract
A 7-month-old boy had a giant pigmented lesion involving the trunk and thighs that exhibited many hyperpigmented hairy and verrucous nevi. One of the nevi ulcerated and on histological examination consisted of pleomorphic rhabdomyosarcoma cells that stained for muscle-specific actin (HHF-35), desmin, and myoglobin. Around the tumor, in the dermis, benign pigmented nevus cells were observed. The occurrence of malignant tumors, other than malignant melanoma, in pigmented nevi is rarely described.

Abstract
Iris melanocytoma is a rare melanocytic nevus with distinctive clinical and pathologic features. Secondary glaucoma may develop rapidly and respond poorly to glaucoma medication in some cases. However, few data are available in the literature with respect to the appropriate treatment for refractory glaucoma associated with iris melanocytoma. Herein, we present a 28-year-old man with blurred vision and an elevated intraocular pressure (IOP) of 40 mmHg in his right eye while on multiple glaucoma medications. A dark brown lobulated iris mass with surrounding small pigmented lesions was noted between the 4 and 5:30 o'clock positions. Sector iridectomy was performed and pathologic examination revealed an iris melanocytoma. After surgery, antiglaucomatous medications still failed to control IOP. The patient then underwent diode laser transscleral cyclophotocoagulation (TSCP). At the last follow-up of 15 months, IOP had returned to normal without the need for medication.
