Mycosis fungoides (MF) is a primary cutaneous T-cell lymphoma that may, although rarely, present as asymptomatic hypopigmented lesions. On the other hand, vitiligo is an autoimmune disorder characterized by asymptomatic depigmented patches. Few reports have documented both conditions occurring in a single patient, making this an intriguing diagnostic and management dilemma.

This is a case of a 26-year old female with a 10-year history of persistent hypopigmented, depigmented and erythematous patches and thin plaques [Figures 1a and 2a]. Histopathology showed epidermotropism of mononuclear cells on H&E stain [Figure 3] and a positive CD-3 stain for T cells, confirming mycosis fungoides [Figure 4b]. No evidence of lymphadenopathy and visceral involvement was found on both the chest and abdominal CT scans. The depigmented patches were likewise biopsied showing lack of Melan-A staining and absence of epidermal melanocytes, consistent with vitiligo [Figure 4a]. Final diagnoses were both mycosis fungoides, stage IB and vitiligo. The patient underwent narrowband UVB phototherapy and was started on topical corticosteroids [Figures 1b and 2b]. Improvement was evident over a three-month period, with body surface area decreasing from 77% to 46%. As the patient is young, has normal LDH levels, and shows no signs of extracutaneous disease, prognosis is promising.

This rare case of mycosis fungoides and vitiligo occurring together presents notable diagnostic and management challenges. Some studies hypothesize that the aberrant T cells involved in MF might contribute to the T cell-mediated destruction of melanocytes, similar to the mechanisms seen in vitiligo.

During the coronavirus disease 2019 (COVID-19) pandemic, vaccines help control the spread of infection. To date, 47 vaccines have been approved, with another 227 candidates in various stages of development. In the short period of time since the beginning of their use, evidence has begun to emerge of complications following vaccination in the form of the development or exacerbation of a number of pathological conditions (Block et al., 2022; Haseeb et al., 2022). For example, a population-based study in France identified 1612 cases of myocarditis and 1613 cases of pericarditis requiring hospital treatment within five months of vaccination (le Vu et al., 2022).

Vitiligo is a depigmentation disease affected by a variety offactors,of which genetic factors play a key role.Single nucleotide polymorphism as a common type of genetic variation can be detected by candidate gene analysis and genome-wide association study.The recent studies have demonstrated that multiple susceptibility genes play a vital role in the occurrence and development of vitiligo.This article introduces the single nucleotide polymorphisms of vitiligo susceptibility genes according to the gene functions.

Summary Halo nevi (HN) are benign skin lesion that represent melanocytic nevi in which an inflammatory infiltrate develops, resulting in zone of depigmentation around nevus. Although Sutton originally described the lesion in 1916 as leukoderma acquista centrifugum, the lesions were noted earlier as evidenced in the painting by Matthias Grunwald cica 1512-1516. The prevalence of HNs in the general population is 1%, and HNs usually appear in childhood or early adulthood. Up to 26% of patients with HN have vitiligo, but in very few instances is there an association of HN around congenital melanocytic nevi (CMN) and vitiligo. The exact mechanisms responsible for the development of vitiligo and HN and its resolution are unknown. One of the most accepted hypotheses considers that both phenomena are a result of a self-limited immunologic response to pigmented cells, either in the “normal” skin or within the melanocytic lesion. Hereby we present a rare case report of a girl with halo CMN and infraorbital vitiligo. The halo CMN was excised which was followed by spontaneous improvement of vitiligo.

OBJECTIVE: To explore the genetic basis for a patient with clinically suspected neurofibromatosis type I, alopecia areata and vitiligo. METHODS: Variant of the NF1 gene was detected by chip capture and high-throughput sequencing. Candidate variant was verified by Sanger sequencing of the family trio. RESULTS: The patient was found to harbor a novel missense c.1885G>A (p.Gly629Arg) variant of the NF1 gene, for which neither parent was carrier. The variant was not recorded in the public database. Based on the guidelines for genetic variation of the American College of Medical Genetics and Genomics, the c.1885G>A missense variant was predicted to be pathogenic (PS1+PS2+PM2+PP3+PP4). CONCLUSION The c.1885G>A missense variant probably underlay the disease in this child. Above finding has enriched the spectrum of the NF1 gene variants.

Vitiligo is a non-communicable, chronic skin condition that has psychosocial effects for the patient. The case of an otherwise healthy skin phototype IV Filipino male with a two-year history of stable vitiligo is presented here. Three sessions of skin punch grafting and platelet-rich plasma injection under local anesthetic were done on the patient three months apart, resulting in excellent cosmetic results and patient satisfaction.
