So-called cutaneous cysts are extremely frequent tumours that could need surgical attention. Most of the time, due to their quite pathognomonic clinical presentation and indolent course, they are simply enucleated. Often, the clinical diagnosis is easily confirmed at surgery by the typical appearance of a cystic formation filled with a creamy fluid. It is frequent for such "typical" lesions to escape histological investigation following removal. However, some mimicking lesions could also be found as "cutaneous cysts" and have quite different prognoses. This paper present five patients with such lesions, three basal cell carcinomas, one benign proliferating trichilemmal cyst and a malignant proliferating trichilemmal cyst. None of the lesions was clinically distinguishable from a classical epidermis cyst.

Background: Birt-Hogg-Dubé syndrome (BHD), a rare genetic disease characterized by multiple pulmonary cysts, can lead to spontaneous pneumothorax, cutaneous hamartomas, renal cysts, and renal cell cancer. The overall aim of this study was to assess clinical characteristics of patients with BHD-emphasizing on trends in pulmonary function patterns.
Methods: By use of data from electronic patient journals, we conducted a retrospective cohort study on clinical characteristics and pulmonary function tests (PFT) from patients with BHD, who were clinically followed-up in a Danish tertiary referral center for rare and interstitial lung diseases.

Trichogerminoma (TG) is a rare, benign, cutaneous adnexal tumor originating from the hair germ epithelium. It typically presents as an asymptomatic, slowly enlarging nodule predominantly on the head, face, or trunk. Despite its benign nature, precise diagnosis is crucial because of its potential to become malignant.

Vitamin D-dependent rickets type 2A (VDDR2A) is a rare cause of infantile-onset alopecia, characterized by severe hypotrichosis, small cutaneous cysts, early-onset treatment-resistant rickets, and hypocalcemia. Alopecia, often starting a few weeks to months after birth, may be the presenting feature. We present three cases of VDDR2A with genetic variants in the vitamin D receptor (VDR) gene, their clinical features and biochemical parameters.

Cutaneous acneiform eruptions are a side effect of many medications, including vitamin B12 therapy. However, reports of vitamin B12-induced acne are rare. We present a 67-year-old woman with a new diagnosis of pernicious anemia who developed a sudden acneiform eruption on the face after treatment with high-dose vitamin B12.
