Epidermoid Splenic Cyst Presented as Huge Splenic Abscess: a Case Report

Epidermoid splenic cysts are very rare. Symptoms emerge because of enlargement, infection, haemorrhage or rupture. Although splenectomy is indicated for large cysts, minimally invasive and preservation procedures, such as partial splenectomy or total cystectomy with splenorrhaphy, have been increasingly used during the last decade. We report herein the case of a 16-year old female presented with left upper abdominal quadrant pain, fever and abdominal distention treated in our department.     

Squamous Cell Carcinoma arising in a Giant Epidermal Cyst: a Case Report

Epidermal cysts are commonly encountered in surgical practice. Malignant degeneration of epidermal sebaceous cyst is uncommon. The authors report the case of a 38-year Filipino woman presenting with a voluminous sebaceous cyst of the left buttock. Ultrasonography and computer tomography were made preoperatively without any hint of eventual malignant degeneration. Marginal excision was performed with direct closure of the skin. The histological examination revealed epidermal sebaceous cyst with squamous cell carcinoma in situ, which is a quite rare, but well known complication occurring in sebaceous cysts.     

Intrascrotal Epidermoid Cyst: Report of Two Cases

A 70-year-old man and a 52-year-old man each presented with a painless extratesticular, intrascrotal mass. Magnetic resonance imaging revealed a cystic mass and was the most useful modality for the diagnosis. Complete excisions were performed, and the lesions were histologically diagnosed as epidermoid cysts. Intrascrotal, extratesticular epidermoid cysts are uncommon lesions believed to be teratomas or the result of abnormal embryological closure of the median raphe. However, it is difficult to explain the etiology of some masses by either of these mechanisms.     

Epidermoid cyst of the ureter: A case report

Epidermal cysts of the upper urinary tract are extremely rare. Only three cases have been reported in the published work written in English, Italian or German. We encountered a case of an epidermoid cyst in the ureter of a 72-year-old male. Findings on urine analysis and radiological examination were useful for establishing a correct diagnosis of epidermoid cyst of the urinary tract.     

Epidermoid cyst of the penis: a case report and review of the literature.

Penile cysts are uncommon. A case of a 7-year-old boy with an epidermoid cyst of the penis is reported. He had an asymptomatic, slowly growing soft mass in the frenulum of the penis. Excision of the mass was performed, and the diagnosis was epidermoid cyst of the penis. No recurrence has been noted within the year since excision. To our knowledge, there have been no previous reports of malignancy developing in cystic disease of the penis. In such cases, clinicians should attempt more appropriate management, involving either watchful observation or complete excision of the cyst, by considering the embryogenesis and nature of the disease.     

Traumatic Epidermal Inclusion Cyst After Minimally Invasive Surgery of a Displaced Intra-Articular Calcaneal Fracture: A Case Report

Epidermal inclusion cysts are common epithelial cysts of the skin. The latter classically originate from progressive cystic ectasia of the infundibular portion of hair follicle. Therefore, these cysts are usually found in hairy regions and rarely in glabrous skin such as the palms and soles. The etiology of glabrous epidermal inclusion cysts appear to be different from that of those located in hairy regions. It has been suggested that implantation of epithelial cells into subcutaneous tissue, such as during trauma, is most likely the pathophysiologic basis. Epidermal inclusion cysts on the palms and soles are often misdiagnosed, leading to improper treatment. Therefore, we report a rare case of an epidermal inclusion cyst of the heel after minimally invasive surgery of a displaced intra-articular calcaneal fracture.     

Epidermoid cyst of the spleen,a case report

IntroductionSplenic tumors are rare and are either primary or secondary, benign or malignant. Most have none to minimal symptomatology and are found incidentally. Splenic cysts can be infectious, congenital, or traumatic. Epidermoid cysts and parasitic cysts are examples of primary cysts and usually have a classic presentation on imaging. Despite advanced imaging modalities and patient's clinical presentation, it can be difficult to diagnose an epidermoid cyst without histological examination. The purpose of this paper is to discuss typical findings of primary splenic cysts on imaging, but how they may differ in appearance.Presentation of case51 year old female who presented with vague abdominal discomfort and was found to have a large splenic mass with cystic components on imaging which did not demonstrate a typical primary splenic cyst appearance. Patient underwent an uneventful hand-assisted laparoscopic total splenectomy and had an uneventful recovery with histopathology revealing an epidermoid splenic cyst.ConclusionPrimary splenic cysts are difficult to diagnose and differentiate with imaging alone. They have a variable presentation and can present like as a cystic mass. It is important to include them in the differential diagnosis of splenic masses since histopathology is the final determinant of the diagnosis.     

Primary Multilocular Hydatid Cyst of Neck with Unique Presentation: A Rare Case Report and Literature Review

Hydatid cyst (HC) is a parasitic infection caused by larva form of Echinococcus. It occurs frequently in liver and lungs. Primary HC of neck is extremely rare occurrence and here we report it with unusual presentation. A 35-year-old male presented with slowly growing painless swelling in right side of neck for 6–7 years. The swelling measured 11 × 6 cm and cough impulse elicited on local examination. MRI scan revealed a multiloculated cystic lesion in neck. Fine needle aspiration cytology yielded fluid aspirate and smear showed fragment of laminated membrane, suggestive of HC. The intact cyst was removed surgically and histopathologic examination confirmed the diagnosis of HC. Both clinicians and radiologists should consider HC in differential diagnosis of head and neck swelling for proper management.

Epidermoid cyst of the brain stem. Case report

Brain stem epidermoid cysts are extremely rare lesions. Only nine cases have been reported. Management of the epidermoid cyst is decompression of cyst contents and removal of cyst capsule. But in some cases resection of the cyst may result in a poor outcome because of cyst wall adhesion into the brain stem.     

Epidermoid tumour of the lateral ventricle

Summary Epidermoids occurring within the lateral ventricles are rare. At one time, they were regarded as anatomical curiosities. The lesions are of developmental aetiology, due to migration of epiblast inclusion at the time of formation of the cerebral vesicle. They are slow growing, and presentation is non-specific in the form of deteriorating mental functions. Generally seen in the fifth decade, but they have also been observed in the paediatric age group. MRI is suggestive of a cystic lesion, and is confirmed to be a typical epidermoid within the lateral ventricle at operation, often having a connection to the midline through the choroidal fissure. The cysts should be excised with no additional morbidity. Histopathology reveals typical stratified squamous epithelium.

目的：探讨膀胱表皮样囊肿临床特点、诊断和治疗方法。方法：回顾性分析1例膀胱表皮样囊肿患者的临床资料。男,31岁,体检发现膀胱占位人院,超声提示膀胱3cm×4cm×3cm高回声占位,CT提示膀胱内占位,密度高于液性,但低于软组织,无明显强化。结果：患者行手术治疗,行膀胱部分切除术,术中见肿物位于膀胱壁内,白色,表面有被膜,血运差,完整切除肿物,剖开肿物见内容物为白色、豆渣样。病理回报：膀胱壁肿物被覆移行上皮之黏膜下表皮样囊肿。患者术后1周痊愈出院,随访15个月未见肿物复发转移。结论：膀胱表皮样囊肿临床极为罕见,目前国内外文献尚无此类报道。膀胱表皮样囊肿尽管罕见,也应为膀胱肿瘤的鉴别诊断之     

Milk of Calcium Cyst Mimicking Renal Calculi: a Case Report

A milk of calcium cyst mimicking renal stone in a 51-year-old man was presented to remind the possibility of milk of calcium when a well-defined round density was observed on the renal shadow of the plain abdomen film and the importance of graphics or CT scans taken in different positions to see the changes in the calcium gravidation to prevent unnecessary surgical interventions due to misdiagnosis.     

Giant extradural epidermoid cyst of the posterior fossa

We report an unusual case of giant extradural epidermoid cyst of the posterior fossa in a 73-year-old man. The patient presented headache and gait disturbance for 3-4 months, cerebellar ataxia, left cerebellar dysmetria, and perturbed balance. The CT-scan showed a huge posterior fossa extradural lesion with a small area of peripheral contrast enhancement. Outcome was good after total resection of the lesion via a suboccipital approach. Pathology reported an epidermoid cyst. Extradural epidermoid cyst is a rare benign tumor of the skull which sometimes can reach considerable size. It is a slow growing lesion and may cause mild neurological deficits. The goal of surgical treatment is total resection of the tumor with its capsule. The long-term prognosis is excellent after successful resection.

Dermoid Cyst of the Parotid Gland: Report of a Rare Entity with Literature Review

Dermoid cysts (DCs)are benign lesions and histologically composed of tissues originating from ectoderm and mesoderm, but not endoderm. Approximately 7 % of all DCs are seen in head and neck area. However, parotid gland is an extremely rare localization in which DCs develop, and only 17 cases have been reported in the literature to date. Correct preoperative diagnosis is difficult to be established due to the rarity and ambiguous radiological findings. We report a case of a 21-year old man. All previous reports reviewed and the pathogenesis as well as the histopathologic and radiologic features are discussed.
