Perianal Endometriosis: An Uncommon Site for a Common Problem.

Endometriosis is the presence of uterine glands and stroma outside of the uterus. It is highly prevalent in women of reproductive age. It is usually found in the pelvis, with most cases being found on the peritoneum, ovaries, or deep in the pelvis.

Pilonidal Sinus Disease is Associated with Severe Hidradenitis Suppurativa in a Spanish Cohort.

Hidradenitis suppurativa is a chronic inflammatory disorder of the hair follicle with a high level of morbidity. Pilonidal sinus disease is a comorbid disorder and may be the reason for first contact with the healthcare system of patients with hidradenitis suppurativa. The aim of this study was to evaluate the frequency of association of pilonidal sinus disease and hidradenitis suppurativa and to explore whether pilonidal sinus disease defines a different clinical profile for patients with hidradenitis suppurativa.

[Effectiveness of fascial tissue flaps and skin flaps with layered sutures for repair of wounds after excision of sacrococcygeal pilonidal sinus].

Objective: To investigate the feasibility and effectiveness of fascial tissue flaps and skin flaps with layered sutures for repairing wounds after excision of sacrococcygeal pilonidal sinus.

Methods: Between March 2019 and August 2022, 9 patients with sacrococcygeal pilonidal sinus were admitted, including 7 males and 2 females with an average age of 29.4 years (range, 17-53 years).

Malignant transformation of perianal tailgut cyst: A case report.

Background: Tailgut cyst is a congenital enterogenous cyst that rarely undergoes malignant transformation. Its clinical manifestations mainly correlate to the mass effect caused by the development of cysts and the infections that originate from these. Furthermore, the complete resection of this cyst is curative.

Mucinous adenocarcinoma of a tailgut cyst.

Unlabelled: A tailgut cyst is a rare congenital lesion that develops from a residual posterior remnant of the intestine and presents as a mass in the presacral space. They are generally asymptomatic or have atypical symptoms, are usually benign but may rarely become malignant. We report a case of a 37-year-old female who initially presented to the Surgical Department of Korle Bu Teaching Hospital, Accra, Ghana with a malignant tailgut cyst after having repeated surgical procedures for recurrent perianal infective pathologies but still had persistence of symptoms.

Pudendal tumor mimicking cauda equina syndrome and acute radiculopathy: case report.

Introduction: Cauda equina syndrome (CES) is most caused by lumbar disc herniation, and the associated treatment involves prompt surgical decompression. Rarer causes of CES include perineural (Tarlov) cysts.

Clinical Presentation: A 62-year-old female with history of rheumatoid arthritis, hip and knee replacements, and chronic low back pain presented with worsening back pain, left leg weakness and pain for 6 weeks, and bowel/bladder incontinence with diminished sensation in the perianal region for 24 h prior to presentation.

An Unusual Perianal Presentation of a Tailgut Cyst.

Tailgut cysts or retrorectal cystic hamartomas are rare, congenital, development lesions arising from the remnants of the hindgut during embryogenesis. It is most often misdiagnosed due to its rarity, variable clinical presentation, and malignant potential. The following report describes an unusual case of a tailgut cyst in a 60-year-old male with a history of a perianal mass for 12 years.

Promoting Laparoscopic Anterior Approach for a Very Low Presacral Primary Neuroendocrine Tumor Arising in a Tailgut Cyst.

Background: Tailgut cysts are rare congenital lesions that develop in the presacral space. As they can potentially conceal primary neuroendocrine tumors, surgical excision is suggested as the treatment of choice. However, specific management guidelines have yet to be developed.

Retrorectal epidermoid mistaken for perirectal swelling: A case report.

Introduction And Importance: Epidermoid cysts are developmental cysts of the retrorectal space. They are benign lesions resulting from ectodermal inclusion during neural tube closure. Generally, they are misdiagnosed given that symptoms are often vague and nonspecific.

Rectal duplication cyst in an adult with a history of imperforate anus: a diagnostic challenge.

Rectal duplications are rare congenital anomalies that represent 1%-6% of alimentary tract duplications. We report a case of a woman in her 50s who presented to our hospital with perianal pain and urinary retention. She had a history of imperforate anus repaired after birth and dynamic graciloplasty performed during her adulthood for faecal incontinence.

Solitary asymptomatic lobular perianal nodule on an infant.

Folliculosebaceous cystic hamartoma (FSCH) is a benign lesion that presents as a solitary papule or nodule that typically affects the face and scalp of adults. A few reports have observed a congenital presentation. We present an infant boy exhibiting a tumor with overlap features between an FSCH and fibrofolliculoma in the perianal region that was first noticed at 6 months of age.

Isolated lumbar intradural tailgut cyst: A case report and review of the literature.

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.

[Chinese expert consensus on standardized treatment of presacral cysts].

Presacral cysts are cystic or cyst-solid lesions between the sacrum and rectum. They are closely connected with adjacent pelvic floor structures such as sacrococcygeal fascia, rectum and anal sphincter. They are usually benign and are believed to be caused by aberrant embryogenesis.

Feline cystadenomatosis affecting the ears and skin of 57 cats (2011-2019).

Objectives: This study aimed to understand epidemiological factors associated with feline cystadenomatosis, including signalment and papillomavirus PCR status. Cystadenomatosis is an uncommon condition primarily involving the ceruminous and apocrine skin and ear glands.

Methods: This was a retrospective case series.

Sinus laser closure (SiLaC) versus Limberg flap in management of pilonidal disease: A short-term non-randomized comparative prospective study.

Introduction: Fistula Laser Closure (FiLAC) is a method that was originally applied in the treatment of perianal fistulas. Because of promising results, diode lasers were later on used to treat pilonidal sinus disease in a method called sinus Laser Closure (SiLaC). The aim of this study is to compare between SiLaC and Limberg flap in management of pilonidal disease.

Presacral Tumor: Insights From a Decade's Experience of This Rare and Diverse Disease.

Background: Presacral tumors are a group of rare and heterogeneous tumors that arise from the potential presacral space between the rectum and sacrum. The low occurrence and diverse origins make the diagnosis and treatment of these tumors a challenge. The aim of the study was to retrospectively review patient demographics and to identify advantages and disadvantages in the diagnosis and treatment of these tumors.
