Reticulated acanthoma with sebaceous differentiation (RASD) is a rare benign sebaceous tumour that is histopathologically characterized by basaloid cell proliferation in a plate-like configuration, underlain by sebaceous glands [1]. It was first described as “superficial epithelioma with sebaceous differentiation” (SESD) [2]. Since the term “epithelioma” is likely to be confused with malignancy, RASD was proposed as a new designation by Steffen and Ackerman [3]. Based on the lack of apocrine [...]

Angiolymphoid hyperplasia with eosinophilia (ALHE), also referred to as epithelioid haemangioma, is a rare skin disease that presents as pruritic papulonodular lesions and predominantly affects the head and neck regions [1]. Although ALHE shares clinicopathological features with Kimura's disease, it is now considered a distinct entity. The disease often results in cosmetic problems and significantly reduces the patient's quality of life. Although multiple treatments, such as surgical excision, topical [...]

Epidermolysis bullosa (EB) is a group of hereditary mechanobullous disorders resulting from mutations in the genes encoding basement membrane zone proteins in the dermal-epidermal junction [1]. Although the precise prevalence is not known, some EB patients show cutaneous hyperkeratotic lesions due to recurrent traumas which can produce scaling and pain [2]. In EB patients, the formation of these hyperkeratotic lesions should be prevented with emollients and proper skin care, such as bathing. Once [...]

Nodular morphoea (NM) is a rare form of morphoea, also known as nodular scleroderma, keloidal scleroderma or keloidal morphoea [1]. NM clinically manifests with single or multiple keloidal nodules or plaques that develop in sclerodermatous areas and most commonly affects young and middle-aged women [1]. NM occurs in association with systemic sclerosis (SSc) and much more rarely with localized morphoea [1]. We report a case of NM associated with linear morphoea. To our knowledge, the association of [...]
