We describe a 62-year-old Japanese woman who exhibited recurrent follicular lichenoid lesions of sarcoidosis. The skin lesions appeared all over the surface of the body without any other organ involvement, and spontaneously regressed within 1 year. Two years later, the lesions recurred on the trunk, especially in the intertriginous areas such as the submammary areas and in fatty folds of the abdomen, and on the thighs and upper arms, with the appearance of uveitis of the right eye. Histological examinations showed that small epithelioid cell granulomas were localized in the perifollicular areas. The present case was characterized by a unique distribution of follicular lichenoid eruptions, which are rare manifestations of sarcoidosis and recurrence of the lesions.

Background: Folliculotropic mycosis fungoides (FMF) is a rare cutaneous malignancy that can be mistaken for inflammatory diseases, such as discoid lupus erythematosus (DLE), due to the variability of histopathological findings.
Methods: This study aims to provide dermatopathologists with evidence-based histopathologic criteria to distinguish DLE from FMF by reporting overlapping and distinguishing microscopic features. Forty-three biopsies from patients with a confirmed diagnosis of DLE or FMF were graded for the presence or absence of 18 histopathologic features.

Background: A fixed drug eruption (FDE) is an immunological cutaneous adverse reaction, classified as a cutaneous adverse drug reaction (CADR) and characterized by well-defined lichenoid lesions that occur at the same site each time. Ceftriaxone is a third-generation antibiotic of cephalosporin antibiotics of the beta-lactam antibiotic family, which has typical activity against many Gram-negative aerobic bacteria. This is the first clinical case from Saudi Arabia and the fifth in the world to document a woman's experience with recurrent FDE after repeated ceftriaxone use.
