An unusual case of paravaginal sebaceous cyst posing diagnostic dilemma

The prevalence of vaginal cysts is uncertain since many go unreported but it is estimated that 1 out of 200 women have a vaginal cyst. We report a case of a 23-year-old female with secondary infertility with an incidental asymptomatic vaginal cyst, which was originally misdiagnosed as an endometriotic cyst. We performed the surgical treatment with negative hysterolaparoscopic findings, only to identify a paravaginal sebaceous cyst on vaginal exploration. Pathology results confirmed that the cyst wall was lined by stratified squamous keratinizing epithelium with a lumen containing lamellated keratin. The features were suggestive of epithelial inclusion cyst.

Quiste epidermoide en conducto auditivo externo: reporte de caso / Epidermoid cysts of the external auditory canal: case report

Resumen El quiste epidérmico es una lesión benigna y común de la piel. Se desarrolla por un bloqueo de la unidad pilosebácea, con la consecuente proliferación de células epiteliales y secuestro de queratina. El 7% se desarrollan en cabeza y cuello, sin embargo, son infrecuentes en canal auditivo externo. Su patrón de crecimiento es lento y progresivo durante años, siendo asintomáticos. Al aumentar de tamaño causan sintomatología variable, acorde a su localización; en el canal auditivo tienen un comportamiento obstructivo que genera síntomas como otalgia e hipoacusia. Se presenta caso de una paciente de 69 años, con acúfeno e hipoacusia progresiva derecha. Durante la otoscopia se observó una neoformación obstructiva del 100% de la luz del conducto. Se realizaron estudios de imagen que reportaron tumoración de características quísticas de conducto auditivo derecho, bien circunscrita, sin erosión ósea. Para el diagnóstico definitivo, se realizó resección quirúrgica y biopsia reportando quiste epidérmico. Durante el seguimiento posoperatorio sin hallazgos de recidiva.

Abstract The epidermal cyst is a common and benign lesion of the skin. It develops due to a blockage of the pilosebaceous unit, with the consequent proliferation of epithelial cells and keratin sequestration. Seven percent develop in the head and neck; however, they are infrequent in the external auditory canal. Its growth pattern is slow and progressive over the years, being asymptomatic. As they increase in size, they cause variable symptoms, according to their location. In the ear canal they have an obstructive behavior that generates symptoms such as earache and hearing loss. A case of a 69-year-old female with tinnitus and progressive right hearing loss is presented. At otoscopy, a 100% obstructive neoformation of the canal lumen was observed. Imaging studies showed a well circumscribed, cystic tumor of the right ear canal, without bone erosion. For the definitive diagnosis, a resection and biopsy were performed, reporting an epidermal cyst. During follow up there was no recurrence of tumor.

Clinical and histopathological profile of primary caruncular lesions

Purpose: To provide a retrospective analysis of lesions of the caruncle which have been very rarely reported in the literature. Methods: A retrospective review of all the caruncular lesions between January 2000 and January 2020 was done at a single tertiary eye care hospital. The lesions were classified as benign and malignant lesions. Clinicopathological correlation was done for the excised lesions. Results: A total of 87 caruncular lesions were included in the study. Males (59%) were affected more than females (41%). The mean age at presentation was 44 ± 20 years. The mean duration of complaint was 36 ± 62 months. A total of 36 patients underwent surgical excision whereas the rest opted for conservative management. Recurrence was noted in five patients. Fifteen different types of lesions were identified histopathologically. Benign lesions (78%) were far more common than malignant ones (22%). Epithelial inclusion cyst was the most common benign lesion and sebaceous gland carcinoma was the most common malignant lesion. Correct clinicopathological correlation was seen in 52.7% of the cases. Caruncular tuberculosis, oncocytoma, and basosquamous cell carcinoma were some of the rare lesions. Conclusion: Caruncular lesions are uncommon and very diverse, which makes clinical diagnosis challenging. Epithelial inclusion cyst and sebaceous gland carcinoma were the most common benign and malignant lesions respectively. Correct clinicopathological correlation was seen in more than half of the cases

Bohn’s nodule: A rare case in a 7-month-old male infant

@#Bohn’s nodule is a soft white cyst filled with keratin and is often found in a newborn's oral cavity. This case has a high prevalence in newborns and is rarely seen in infants after three months. In this case, we report our observation and evaluation of a Bohn’s nodule case in a seven-month-old male infant. Clinical diagnosis of the conditions is vital to avoid unnecessary therapeutic procedures and provide timely information for parents to manage the lesion.

Perianastomotic cyst following rectosigmoidectomy due to adenocarcinoma of the proximal rectum: a case report / Cisto perianastomótico pós-retossigmoidectomia por adenocarcinoma dereto alto: relato de caso

ABSTRACT The implantation cyst occurs from the imprisonment and subsequent proliferation of the colonic mucosa below the submucosa during mechanical stapling. The understanding and definition of the evaluation protocol of these lesions is important, since they can generate the need for a new complex surgical procedure and cause anxiety in patients and surgeons. This case reports the occurrence of a subepithelial lesion in follow-up imaging of a patient who underwent videolaparoscopic rectosigmoidectomy for adenocarcinoma of the proximal rectum, submitted to an endoscopic attempt to drain/detangle the lesion and subsequent histopathological analysis showing colic mucosa without changes. In line with Katsumata,it is suggested to asymptomatic patients without alteration of the CEA or suspicious imaging signs a follow up with periodic imaging methods. For symptomatic patients with normal CEA, or whose lesions are growing at follow-up exams, it is suggested to continue with the investigation, with biopsy and/or effluent sample for histopathological study in addition to an attempt at symptomatic resolution. Finally, in the presence of an alteration in CEA, despite symptoms, it is suggested that the lesion be managed as a suspected local tumor recurrence.

RESUMO O cisto de implantação ocorre a partir do aprisionamento e subsequente proliferação da mucosa colônica abaixo da submucosa durante o grampeamento mecânico. A compreensão e definição do protocolo de avaliação dessas lesões é importante, pois podem gerar a necessidade de um novo procedimento cirúrgico complexo e causar ansiedade em pacientes e cirurgiões. Este caso relata a ocorrência de uma lesão sub-epitelial na imagem de seguimento de um paciente submetido à retossigmoidectomia por via videolaparoscópica devido a adenocarcinoma do reto proximal, submetido a uma tentativa endoscópica de drenar/remover a lesão e subsequente análise histopatológica mostrando a mucosa cólica sem alterações. De acordo com Katsumata, sugere-se que pacientes assintomáticos sem alteração do CEA ou sinais de imagem suspeitos tenham um seguimento com métodos de imagem periódicos. Para pacientes sintomáticos com CEA normal, ou cujas lesões mostrem crescimento nos exames de seguimento, sugere-se continuar a investigação, com biópsia e / ou amostra de efluente para estudo histopatológico, além de uma tentativa de resolução sintomática. Finalmente, na presença de uma alteração no CEA, apesar dos sintomas, sugere-se que a lesão seja tratada como uma suspeita de recorrência local do tumor.

Quiste epidérmico gigante de región perianal: reporte de un caso / Giant epidermal cyst of the perianal region: a case report

Introducción: Quiste epidermoide de inclusión es una lesión dérmica benigna frecuente, predominante en hombres de 30-40 años, originada por secuestro de restos epidérmicos, oclusión pilosebácea o implantación traumática de elementos epiteliales en la dermis.Caso clínico: Paciente femenino de 75 años de edad la cual presenta tumoración perineal de 4 años de evolución, con aumento progresivo en el último año ocasionando disconfort. Resonancia magnética nuclear, muestra lesión quística. Escisión quirúrgica incluyendo capsula en su totalidad. Anatomía patológica, quiste de inclusión epidérmica. Control a los 6 meses sin evidencia de recidiva.Conclusión: El quiste epidérmico gigante de inclusión perineal es raro, por lo cual hay que descartar otras patologías similares. El tratamiento quirúrgico debe evitar la escisión fraccionada e incluir la capsula en forma completa, de lo contrario la recidiva es una constante.

Introduction: The epidermoid inclusion cyst is a frequent benign dermal lesion, predominantly in men aged 30-40, caused by sequestration of epidermal remains, pilosebaceous occlusion or traumatic implantation of epithelial elements in the dermis.Case report: A 75-year-old female patient who has 4 years of evolution perineal tumor with a progressive increase in size in the last year causing discomfort. MRI shows a cyst lesion. Surgical excision including capsule. Pathological anatomy, epidermoid inclusion cyst. Following at 6 months without evidence of recurrence.Conclusion: The giant epidermoid cyst of perineum is rare, therefore we must rule out other similar pathologies. Surgical treatment should avoid fractional excision and include the capsule completely, otherwise recurrence is a constant.

Quistes de inclusión epitelial, una extraña causa de aumento de volumen vulvar en niñas y adolescentes: un caso clínico / Cysts of epithelial inclusion, a strange cause of increased vulvar volume in girls and teens: a clinical case

Los tumores vulvares son un desafío diagnóstico en la práctica clínica por las múltiples etiologías subyacentes. CASO CLÍNICO: Adolescente de 13 años que presentó dos nódulos vulvares de un mes de evolución, asociados a leve dolor. Ecografía preoperatoria sospecha un quiste de inclusión epidérmica, el que se confirmó con biopsia excisional.

Vulvar tumors are a diagnostic challenge in clinical practice due to the multiple underlying etiologies. CLINICAL CASE: A 13-year-old adolescent who presented two vulvar nodules of one month of evolution, associated with mild pain. Preoperative ultrasound suspected an epidermal inclusion cyst, which was confirmed with excisional biopsy.

Scrotal calcinosis, dystrophic or idiopathic, does it matter? A case report

@#Scrotal calcinosis is a rare condition with controversy surrounding its unclear etiopathogenesis. Several schools of thought have emerged from recent publications supported by histological findings seen in the respective cases reported. The recommendation of surgery as management, and its outcome, however, have remained the same throughout history. This paper reports a 36-year-old male who presented with gradually progressing multiple pruritic nodules over the scrotum who underwent wide excision with favorable outcome on follow up. Histological examination confirmed the diagnosis of scrotal calcinosis and showed evidence of intact epidermoid cysts that have undergone dystrophic calcification.

Unusual complications of hypospadias repair: diagnosis and management

Background: Epidermal inclusion cyst, smegma stones and urethral calculi of the penis are rare and may result as a late complication of hypospadias repair. This study reported the presentation and management of these late complications.Methods: A prospective observational study included male patients aged more than 6 years of age, who had undergone hypospadias repair 3-15 years back and presented with slow growing, non-tender, mobile, firm to hard swelling. Histopathological and radiographic examination were done and surgery was used for management of epidermal inclusion cyst, urethral calculi and smegma stone. Patients were followed up for one year, postoperatively.Results: Out of 15 patients, two (13.3%), four (26.7%) and nine (60%) patients were diagnosed with smegma stones, epidermal inclusion cyst and urethral calculi, respectively. The median (range) age of patients was 17 (8-30) years. Patients were presented with slow growing, non-tender, mobile swelling measuring from 1 cm x 3 cm to 2 cm x 1.5 cm. The average size of epidermal inclusion cyst, and urethral calculi was 2 cm x 2.5 cm x 1.5 cm, and 2 cm x 3 cm, respectively. Treatment were complete excision of cyst and removal of smegma stones by surgery and urethral calculi by dorsal urethrotomy. All patients had an uneventful postoperative period and were asymptomatic up to one year of follow-up.Conclusion: Results suggest that these complications can be managed with complete excision and surgical removal and care must be taken while performing the hypospadias repair to avoid these unusual late complications in patients.

Epidermal Cyst of the Breast: A Rare Case Presentation.

Epidermal inclusion cyst (EIC) arising from the breast is an interesting, rare, benign, and diagnostically challenging condition, since these may be misdiagnosed as malignant breast neoplasm, both on clinical and radiological examination, thereby creating undue anxiety and apprehension until the definitive diagnosis is formulated. To substantiate it, two cases of epidermal cyst of breast have been described.

Epithelial inclusion cyst of the cecum: A rare entity.

Epithelial inclusion cyst of the cecum (EICC) or epidermoid cyst of the cecum is extremely rare. Only seven cases of EICC have been reported in the English literature until now. A case of EICC is being reported in a 25-year-old female who presented with a pelvic mass associated with lower abdominal pain radiating to back. Abdominal contrast-enhanced computed tomography scan showed a welldefined mass juxtaposed to cecum. During operation, a subserosal cystic mass was found adherent to the anterior wall of the cecum and confirmed to be an epithelial inclusion cyst histopathologically. It is being reported due to its extreme rarity.

Traumatic Epidermal Inclusion Cyst under Anterolateral Thigh Free Flap on Great Toe

Epidermal inclusion cyst is a common mass in life. It is covered with a stratified squamous epithelium, thus, there is a granular cell layer adjacent to the keratin-containing cyst lumen. It can be caused by mechanical force, trauma, or a spontaneous event. It can rupture spontaneously or be ruptured by external mechanical forces. Epidermal inclusion cysts that exhibit inflammation or recur should be removed by simple excision. In this case, the patient showed an epidermal inclusion cyst under an anterolateral thigh free flap, which can cause the palpable mass to go unnoticed. First we thought he had neuroma formation after a surgical procedure on his foot. However it was an epidermal inclusion cyst, which was diagnosed by a special pathologist. It is a curious and rare case.

A Case of Conjunctival Inclusion Cyst Managed with Marsupialization

PURPOSE: We present a case with conjunctival inclusion cyst at inferior fornix treated by marsupialization. CASE SUMMARY: A 23-year-old woman visited our clinic complaining of left lower eyelid swelling. Ophthalmologic examination and CT scan showed a cystic mass from inferior conjunctival fornix to anterior orbit with shallow fornix and focal symblepharon. The cyst was effectively removed with marsupializaion. Postoperatively, there was no recurrence of cyst and the fornix was deepened. CONCLUSIONS: Marsupialization can be a considerable treatment option in conjunctival inclusion cyst, especially when accompanied by shallow fornix and symblepharon.

Congenital inclusion dermoid cyst of the posterior fontanel: a case report

Background: Dermoid cysts are rare and benign tumors originating from failure of the normal embryologic development. Congenital inclusion dermoid cysts are usually located over the anterior fontanel. Surgical treatment is curative and provides good aesthetic results. The authors present a rare case of congenital inclusion dermoid cyst over the posterior fontanel and discuss the location, differential diagnosis, treatment and prognosis of this unusual pathological entity. Case description: A two-year old boy presented with a lesion on the posterior aspect of the head which had dated since birth. Imaging studies revealed an extracranial lesion over the posterior fontanel without intracranial extension. Surgical removal was performed and the histopathological examination confirmed the diagnosis of a dermoid cyst. The patient was discharged free of any medical complications. Conclusion: Although congenital inclusion dermoid cysts are more common over the anterior fontanel, they can occur over the posterior fontanel as well. Surgical treatment is curative in both locations with favorable aesthetic results.

Chronic and Recurrent Subareolar Abscess of the Breast from Underlying Causes

A subareolar abscess is the most common non-puerperal abscess of the breast. The main cause of a subareolar abscess is squamous metaplasia, which obstructs the lactiferous ducts and leads to the stasis of secretions and rupture of the ducts. However, there are other causes of subareolar abscess formation.

Multiple Epidermal Inclusion Cysts in Previous Bone Graft Site of the Thumb: A Case Report

We report a 71-year-old male presenting with painful growing mass on his left thumb. The patient had received iliac bone graft on his left thumb 20 years ago, and removed all the grafted bone 8 years ago due to recurrent ulcer. Biopsy revealed multiple eidermal inclusion cysts on the dorsal surface of the bone graft site. Surgeon should be aware of epidermal inclusion cyst occurred at the previous bone graft site of the finger.

Intraosseous Epidermal Inclusion Cyst in the Distal Phalanx of Thumb with Cortical Destruction: A Case Report and Review of Literature

Intraosseous epidermal inclusion cyst is a rare benign, cystic lesion. It is thought to result from traumatic implantation of epidermal elements into bone. Radiologic findings of intraosseous epidermal inclusion cysts are well-defined, lytic lesions. It is difficult to diagnose intraosseous epidermal inclusion cyst without pathologic diagnosis. We experienced a 43-year-old man with a history of trauma followed by painless expansion of his left thumb. Radiographs demonstrated a severe expansile, ill-defined lytic lesion with cortical destruction in the distal phalanx of left thumb, mimicking neoplastic bone lesion or infectious lesion. An intraosseous epidermal inclusion cyst was confirmed by pathologic diagnosis, which was lined by stratified squamous epithelium, containing keratinized cellular debris.

Conjunctival inclusion cysts following small incision cataract surgery.

The occurrence of acquired conjunctival inclusion cysts following various ophthalmic surgeries such as strabismus surgery, scleral buckling, pars plana vitrectomy, ptosis surgery and phacoemulsification has been reported. We report two cases of conjunctival inclusion cysts following manual Small Incision Cataract Surgery (SICS) in two male patients aged 65 and 67 years. The cysts originated from the scleral tunnel used for manual SICS. Both were treated by excision and confirmed histopathologically. No recurrence was noted at three months follow-up. To our knowledge, conjunctival inclusion cysts following SICS have not been reported previously. Careful reflection of conjunctiva during tunnel construction and posterior chamber intraocular lens implantation may prevent their occurrence.

Penile epidermal inclusion cyst.

We report a case of epidermal inclusion cyst of penis in a five-year-old boy, who had presented to the outpatient department of our hospital. Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The child was operated and discharged uneventfully. The objective of reporting this case is to highlight the rare possibility of an inclusion cyst arising from penis as a late complication of circumcision.
