Presentation
A diagnosis of pyogenic granuloma was rendered, which. is a rapidly growing, hypervascular, hemorrhagic lesion that presents as a painless, reddish purple, pedunculated, or sessile mass. [ijdvl.com]

procedure, and it is speculated that growing nests near the scar can influence the adjacent melanocytes and gradually spread to neighbouring cells, which eventually results in the whole macule turning black. [semanticscholar.org]
If the lesion was originally a nevus with higher levels of cytologic atypia or the clinical scenario is atypical, an additional surgical procedure to confirm the benignity of the process could be considered. [dermatologyadvisor.com]
Keywords: Ambulatory surgical procedures, Nevus, Histology INTRODUCTION Recurrent melanocytic nevus is defined as the proliferation of remaining melanocytes that occurs after the partial removal of a melanocytic nevus, which leads to repigmentation at [ncbi.nlm.nih.gov]
- Inflammation
These cases of regression had features indistinguishable from cases of recurrent nevi with epidermal effacement, melanocytic atypia, and dermal fibrosis with inflammation (Figure 4a–f). [nature.com]
Skin
- Pruritus
Clinically, the halo is manifest as erythema, an increase in size, or pruritus at the site of the Spitz nevus; the lesion is usually excised before it reveals the depigmentation halo.44Pagetoid Spitz Nevus Pagetoid Spitz nevus is characterized by abundant [actasdermo.org]
- Hyperkeratosis
Histopathological examination showed hyperkeratosis and marked proliferation of melanocytes with large amounts of melanin pigments in the epidermal basal layer. Some melanocytes showed mild atypia, but no mitotic figures were found. [medicaljournals.se]
- Skin Lesion
A melanocytic naevus (American spelling ‘nevus’), or mole, is a common benign skin lesion due to a local proliferation of pigment cells (melanocytes). [dermnetnz.org]
- Dermatitis
Meyerson naevus Halo naevus Spitz naevus Reed naevus Meyerson naevus is a naevus affected by a halo of eczema/dermatitis. Halo naevus or Sutton naevus has a white halo around the mole. The mole gradually fades away over several years. [dermnetnz.org]
- Eczema
A Meyerson naevus is itchy and dry because it is surrounded by eczema. [dermnetnz.org]

- Confusion
Recognizing this phenomenon is very important, especially because recurrent melanocytic nevi display asymmetric borders and irregular pigmentation in the majority of the cases, which may lead to diagnostic confusion with melanoma.1-4 Histopathological [ncbi.nlm.nih.gov]

Few of them have arisen in nevus flammeus without any predisposing factor like trauma, laser treatment, or pregnancy.[2] This spontaneous development may be promoted by arteriovenous anastomoses in vascular lesions, especially in the richly vascularized [ijdvl.com]

The challenge for the clinician is how to deal with this situation to find the correct diagnosis and the best treatment for the patient. [dermoscopedia.org]
The embryonic development, pathogenesis and treatment of divided nevus has rarely been reported in the literature. [bmcophthalmol.biomedcentral.com]
Prognosis
Its expression has also been correlated to prognosis in patients with melanomas [3]. S100 has been reported to exhibit high positive rates in malignant melanoma and pigmented disorders (96.7–100%) [4]. [bmcophthalmol.biomedcentral.com]
Etiology
With the etiology not being fully understood, an unknown stimulus triggers endothelial cell proliferation and angiogenesis leading to a rapidly growing lesion.[1] More recently, few studies have indicated that abnormalities in embryonic vasculogenesis [ijdvl.com]
Their etiology is unknown, although it has been postulated that their appearance could be related to a genetic predisposition or trigger factors. [actasdermo.org]
Epidemiology
Epidemiology The overall incidence of Spitz nevi is not well documented, but it is thought to lie between 1.4 and 7 cases per 100 000 persons per year.9–11 These lesions represent fewer than 1% of melanocytic tumors that are excised during childhood.12 [actasdermo.org]
Prevention
Management of the catches of skates and rays under a combined TAC prevents effective control of single-stock exploitation rates and could lead to overexploitation of some species. [ices-library.figshare.com]
Can melanocytic naevi be prevented? The number of melanocytic naevi can be minimised by strict protection from the sun, starting from birth. Sunscreen alone is not sufficient to prevent new naevi from appearing. [dermnetnz.org]
