Background: There are limited reports of uveal “melanocytic” lesions in patients with oculocutaneous albinism, with no reports from Asia. Objectives: In this study, we report 3 eyes with uveal “melanocytic” lesions in Asian patients with oculocutaneous albinism. Methods: Retrospective small case series. Three eyes of 2 Asian patients with oculocutaneous albinism were included. Case 1 was a 54-year-old female who presented with juxtapapillary choroidal melanoma and underwent enucleation. Case 2 was a 39-year-old male with pigmented choroidal nevus in the right eye and suspicious nevus/choroidal variegation in the left eye. Results: For case 1, metastatic workup including ultrasound of the abdomen, liver function test, and chest X-ray was unremarkable. Magnetic resonance imaging of the cranium ruled out extraocular extension. The left eye was enucleated due to the large tumor size and poor visual potential, and histopathological examination confirmed the diagnosis of choroidal melanoma with mixed cell type. At the last follow-up 6 months after enucleation, there was no evidence of metastasis. Case 2 was observed. Conclusion: Pigmented choroidal nevus and melanoma are rarely observed in patients with oculocutaneous albinism.

Unusual Appearance

Meyerson phenomenon, also known as “halo-eczema,” has been widely described over melanocytic and non-melanocytic lesions. However, its appearance over vascular anomalies is rarely observed and could lead to diagnostic errors. A case study of five patients aged between four months and two years is reported. These patients developed unique erythematous and pruritic scaly patches, being diagnosed and treated as fungal infections. Due to the lack of response to the treatment, they were referred to the pediatric dermatology practice, where the diagnosis of Meyerson phenomenon over capillary malformations was made. Topical treatment with corticosteroids led to improvement in all cases. Although Meyerson phenomenon developing over vascular anomalies is a rare condition, it is important for pediatricians and dermatologists to assess it as a part of the differential diagnosis when treating a patient with skin lesions. Recognizing this phenomenon will prevent diagnostic and therapeutic errors.

Clinical And Pathological Features

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.
