Division of Neurosurgery, "San Pio" Hospital, 53 Via Pacevecchia, 82100 Benevento, Italy.

Tailgut cysts are rare developmental cysts arising from remnants of the embryological postnatal gut. Despite being frequently located in the presacral space, isolated cases of aberrant locations have been reported, including, perirenal, perianal, and subcutaneous sites, with only two cases of subdural tailgut cysts reported to date. The clinical course is often marked by linear growth, causing compression of the adjacent structures, however malignant transformation with carcinomatous features has been previously described.

Two Cases of Hidradenitis Suppurativa Treated with Adalimumab at the Department of Dermatology and Venereology, Clinical Hospital Mostar.

Acta Dermatovenerol Croat 2021 Jul;29(2):108-110

Prof. Jasna Zeljko Penavić, MD, PhD, Department of Dermatology and Venereology, Clinical Hospital Mostar, Mostar, Bosnia and Herzegovina;

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease primarily affecting apocrine gland-rich areas of the body and presenting with painful nodules, abscesses, sinus tracts, and scarring (1). HS is a defect of the follicular epithelium; some have therefore called for the naming the disease acne inversa instead of hidradenitis suppurativa. The term acne inversa links the pathogenesis to acne and reflects the fact that it is an expression of follicular occlusion in localizations inverse to acne vulgaris (2). Read More

Retrorectal cyst: proteus in the backyard-case series and literature review.

BMJ Case Rep 2020 Jun 2;13(6). Epub 2020 Jun 2.

Department of Surgery, University of New Mexico Health Sciences Center, Albuquerque, New Mexico, USA

Retrorectal cysts are cystic lesions located in the retrorectal space and are a distinct subset of retrorectal tumours, which are often misdiagnosed due to their rarity and mimicry of symptoms caused by common diseases. We have described the presentation and management of four patients who were diagnosed with retrorectal cysts from a 10-year retrospective chart review at our institute, a tertiary care centre. In middle-aged women, the following should raise suspicion of retrorectal cyst: gastrointestinal or urinary obstructive features, mass or fullness palpable on the posterior wall on digital rectal examination, presacral dimple, perianal fistula and/or recurrent disease.
