Epidermoid cyst of the glans penis

Epidermoid cyst of the testis is a well-described entity. In the literature, one case of epidermoid cyst on the dorsum of the penile shaft has been described. Here, we present the first known case of epidermoid cyst of the glans penis.     

Epidermoid cyst of the penis: a case report

A 62-year old man presented with a painless, slowly growing mass of the penis, which had been noted since childhood. A cystic mobile mass about 2.5 cm in diameter was found at the ventral aspect of the glans penis. Excision of the mass was performed to confirm the diagnosis. There was no communication with the urethra. The pathological diagnosis was epidermoid cyst of the penis. Epidermoid cysts of the penis are rare, and many of them arise on the penile raphe, which are thought to be one of the type of rapheal cyst. To our knowledge, this is the 7th case in the Japanese literature.     

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 cyst of the cecum.

An epidermoid cyst of the cecum is reported in an 8-year-old girl who presented with vague abdominal pain. Abdominal ultrasound scan showed a mass that was cystic in nature. During operation, a subserosal cystic mass was found in the wall of the cecum and confirmed to be an epidermoid cyst histopathologically. This is the first case of epidermoid cyst of the cecum in children reported in the literature.     

A case of giant epidermoid cyst occupying the testis

A case of a giant epidermoid cyst of the testis is presented. A 65-year-old man was incidentally pointed out to have left scrotal painless swelling. Physical examination revealed an over hen-egg sized enlargement of the left scrotal contents. Ultrasonography revealed a 7.5 X 5.5 X 4.0 cm solid tumor with heterogeneous echogenicity. No other abnormal findings were observed including tumor markers. Since preoperative examination did not rule out malignancy, we performed left high orchiectomy. Pathological diagnosis was a epidermoid cyst of the testis with a small portion of atrophic testis. Although the preoperative diagnosis of testicular epidermoid cyst is possible, it may be considerably difficult when a giant epidermoid cyst is occupying the testis.     

Multiple epidermoid cysts located in the pineal and extracranial regions treated by neuroendoscopy

A 22-year-old woman presented with a rare case of multiple epidermoid cysts located in the pineal and extracranial regions. Magnetic resonance (MR) imaging showed a lesion in the pineal region as hypointense on the T(1)-weighted image and hyperintense on the T(2)-weighted image, without enhancement. Neuroendoscopic treatment was performed under a diagnosis of pineal cyst. However, the cyst wall was too thick to perforate, although third ventriculostomy was performed. Diffusion-weighted MR imaging demonstrated the lesions in the pineal and extracranial regions as marked hyperintensity. The diagnosis was epidermoid cyst. Subsequently, neuroendoscopic treatment of the pineal epidermoid cyst was performed. Careful preoperative diagnosis of epidermoid cysts based on diffusion-weighted MR imaging is required.     

Giant earlobe epidermoid cyst

Epidermoid cysts represent the most common cutaneous cysts. They are usually small and benign; however, sometimes they can grow to giant epidermoid cists, and occasionally malignancies develop. Giant epidermoid cysts at the earlobe have never been described but in other locations. We describe a case of a giant epidermoid cyst at the earlobe, a location where such a large cyst has never been reported before. The mass was completely resected and the wound of the pedunculated base was sutured with four stitches of nylon 5/0. Histopathology confirmed the presumptive diagnosis of an epidermoid cyst. Six months after the resection, the patient did not have any relapse of the epidermoid cyst. The earlobe is a potential location for giant epidermoid cysts. Although the clinical diagnosis could be enough, due to the possibility of malignancy and to ensure appropriate diagnosis, we consider that all cysts should be sent to the anatomic pathology laboratory for histological evaluation.

Epidermoidzyste der Niere

In contrast to epidermoid cysts of the dermis, epidermoid cysts of the kidneys are rare. We report on a female patient with recurrent renal colic caused by an epidermoid cyst of her right kidney. A malignant tumor was suspected by computed tomography but was ruled out through ureterorenoscopic biopsy. The epidermoid cyst was removed by a partial nephrectomy.     

Familial Epidermoid Cysts of the Spleen: Report of Two Cases

The familial occurrence of epidermoid cysts of the spleen is rare, with only six cases having ever been reported, to our knowledge. We recently diagnosed epidermoid cysts of the spleen in a mother and son. First, a 15-year-old boy was admitted to our hospital for management of blunt abdominal trauma. Computed tomography (CT) showed a ruptured large splenic cyst with an intraabdominal hematoma. We performed a splenectomy, and histopathological examination confirmed the existence of an epidermoid cyst of the spleen. About 2 years and 6 months later, the family physician found that the patient's 41-year-old mother had a large splenic cyst, and she was referred to our hospital for further investigation. CT showed a 10 × 8 cm cyst occupying most of the spleen. The patient underwent splenectomy, and a pathological diagnosis of an epidermoid cyst of the spleen was confirmed. Although the etiology of epidermoid cysts of the spleen is unclear, this familial occurrence may support the hypothesis of congenital malformation as a result of genetic change.     

Epidermoid cyst of testis: a case for orchiectomy

Epidermoid cyst of the testis is a benign lesion without report of metastasis. It cannot be differentiated reliably from the far more common malignant testicular mass on a clinical basis. Simple excision of the cyst, even with concurrent biopsy of the apparently normal surrounding parenchyma, does not exclude the possibility of a remote scar or focus of viable tumor. The existence of a concurrent malignant lesion along with an epidermoid cyst may be more than coincidental. For such an undetected associated lesion, appropriate highly successful adjunctive therapy is delayed if excision of the epidermoid cyst alone is performed. Consequently, inguinal orchiectomy should be the treatment of choice for epidermoid cyst of the testis with the subsequent burden of proof placed on the pathologist to exclude associated lesions that may alter therapy.     

Epidermoid cyst of the tibia (author's transl)

Case report on a large epidermoid cyst in the proximal tibia in a 42-year old woman. Scrutiny of the available literature shows that this is the first recorded case of an epidermoid cyst in a long bone.     

Epidermoid cyst of the testis in an adolescent: Case report and review of the evolution of the surgical management

Epidermoid cyst, a tumorlike lesion, is a rare benign testicular tumor with typical, distinctive ultrasonographic appearance. When the preoperative features are highly suggestive of epidermoid cyst, testicular sparing surgery after strict oncologic guidelines is warranted. The authors report a case of a preoperatively suspected epidermoid cyst in an adolescent and review the literature concerning the changing paradigm of management.

Giant Epidermoid Cyst on the Forefoot

BACKGROUND: Epidermoid cysts are the most common cysts of the skin, usually appearing in the hairy regions. However, epidermoid cysts on the non-hair-bearing areas, such as the palms and the soles, are rare and seldom reach a size of more than 5 cm in diameter. OBJECTIVE: To present a patient with an epidermoid cyst of unusual location and size. METHODS: A 23-year-old woman with a painless tumorlike mass on her right forefoot was examined and the mass was excised. RESULTS: The 6.5 cm x 5.5 cm x 5.5 cm mass was totally excised. Histologic diagnosis was reported as an epidermoid cyst. CONCLUSION: An original case regarding an unusual location and size of an epidermoid cyst is presented.

Epiermoid cyst in the kidney.

Epidermoid cyst of the kidney is a rare entity. In the case here presented, epidermoid cyst was an incidental finding at urography performed in a 67-year-old man in connexion with splenectomy for polycythaemia. The cyst was interpreted as an old tuberculous focus. Two years later partial nephrectomy was performed because of repeated attacks of renal colic and signs of recurrent pyelonephritis. The diagnosis of epidermoid cyst was not made preoperatively in this case, or in the cases described in the literature.     

Excision of a brain-stem epidermoid cyst. Case report.

An intra-axial epidermoid cyst of the brain stem is presented. X-ray studies revealed a mass within the brain stem; computerized tomography showed the mass to be cystic. The epidermoid cyst was successfully removed surgically. Six months after operation the patient is stable with sixth and seventh nerve palsies but resolution of right spastic hemiparesis.
