Frontal fibrosing alopecia (FFA) is a scarring alopecia that primarily affects postmenopausal women. Although its etiology remains unknown, familial cases suggest a genetic basis. In this case report, we present the findings of three sisters with familial FFA, aged 55, 60, and 62 years, from Türkiye. Genetic analysis revealed that all three sisters shared the human leukocyte antigen (HLA)-A*11:01; B*35:01; C*04:01 haplotypes. Two sisters had HLA-DRB1*03:01 and HLA-DQB1*02:01, while the third had HLA-DRB1*01:01; HLA-DQB1*05:01. The shared HLA-A*11:01, B*35:01, and C*04:01 haplotype has not been previously associated with familial FFA. This finding marks the first familial FFA report from Türkiye and suggests a new genetic susceptibility haplotype for FFA in the Turkish population. The variation in HLA-DRB1 and HLADQB1 alleles among the sisters indicates complex genetic influences on the familial FFA. Further research is required to determine the role of these genetic variations in disease progression and to identify potential therapeutic approaches.

Coronavirus disease-2019 (COVID-19) caused by the severe acute respiratory syndrome-coronavirus-2, which became a pandemic, may have cutaneous findings. Eccrine chromhidrosis is a rare disorder characterized by the excretion of colored sweat via the eccrine sweat glands. We present eccrine chromhidrosis in two COVID-19 cases treated with favipiravir.

Isotretinoin is often used in the treatment of severe acne. However, many adverse reactions were reported, including mucocutaneous, metabolic, neurological and psychiatric, ophthalmologic, hematologic side effects and teratogenicity. The mucocutaneous are the most common side effects and often develop in a dose-dependent manner. I present a case of a 20-year-old male with the unusual non-specific dysuria only and review the literature on the urological effects of isotretinoin

Fluoroscopy is widely used for minimally invasive procedures. The diagnosis of fluoroscopy-induced chronic radiation dermatitis (FICRD) may be overlooked, because patients may unintentionally be exposed to radiation in surgical procedures. Prolonged or multiple procedures increase the risk of acute and chronic skin damage. Herein, we report a patient diagnosed with FICRD treated with excision and reconstructed with rhomboid flap. Due to the risk of radiation-related malignancy, complete surgical excision and suitable reconstruction according to the skin defect may be preferred as a treatment option. Clinical follow-up is important especially following prolonged fluoroscopy-guided procedures.
