“…Rarely, SWS can be associated with oculodermal melanocytosis [ 9 , 10 ]. This condition presents with excessive melanocytes in the peripheral ocular skin and various ocular areas including the uvea and sclera [ 11 , 12 ]. It rarely occurs in Caucasian patients, being more frequent in Asian ethnicity [ 13 ].…”

We present the case of a 12-year-old boy with Sturge-Weber syndrome and ocular melanocytosis who presented with bilateral naevus flammeus of the face and hyperpigmentation of the right iris associated with ipsilateral iris mammillations. The patient had glaucoma and a diffuse choroidal haemangioma of the right eye. Optical coherence tomography of the anterior segment confirmed iris hyper-pigmentation and did not show abnormalities of the chamber angle structures. B-scan ultrasonography and enhanced depth imaging optical coherence tomography were performed and showed a marked difference in thickness and reflectance between the right and left choroid. Visual field examinations with perimetry showed early defects in the right eye. Peripapillary optical coherence imaging showed borderline values of retinal nerve fibre layer thickness reduction in the right eye. Sturge-Weber syndrome associated with ocular melanocytosis and iris mammillations is an extremely rare condition. This paper highlights the role of multi-imaging methods in the enhanced evaluation of rare diseases towards choosing the most appropriate management strategies and improving the follow-up of patients over time.

“…Various factors have been investigated: It has been shown that GNAQ is mutated in about 6 % of Ota's nevus cases. The additional monosomy of chromosome 3 and increase of the long arm of chromosome 8q is a risk factor for uveal melanoma [17,21,22]. If melanomas develop within an Ota's nevus, they frequently show locally destructive growth.…”

Summary The magnitude of the topic of melanocytic nevi (MN) is directly related to its relevance in everyday clinical work. The different MN have different prognostic significance in regard to comorbidity and possible risk of transformation. In addition to the criteria of the ABCDE rule, relevant criteria in the assessment of an MN are the time of occurrence, the growth tendency, the distribution and the comparison with other MN of the respective individual. The present CME article provides an overview of the knowledge that has been gained with regard to the development and genetic background of MN and any risk of degeneration that may exist. In addition, certain clinical and/or dermatoscopic features may provide the clinician with a decision‐making aid in the management of different MNs.

The eyelid area poses a diagnostic and therapeutic challenge due to its specific anatomy. The eyelid is composed of skin, orbicularis muscle, tarsus, and the eyelid margin is continuous with palpebral conjunctiva. Among pigmented tumors, benign lesions such as epidermal or intradermal nevi, freckles, lentigo, or seborrheic keratosis are the most common. Melanoma is relatively rare in this location. A suspicious lesion may be biopsied or excised. Surgery in the eyelid area requires special considerations to maintain a safe surgical margin, vital function of the eyelid, and acceptable cosmetic effect due to the exposure of the eyelid region of the face.
