1/20. Laparoscopic splenectomy for a giant splenic epidermoid cyst: report of a case.The use of laparoscopic splenectomy has increased in recent years, primarily for patients with idiopathic thrombocytopenic purpura (ITP). We describe herein the first known case of a laparoscopic splenectomy to be performed in japan for a patient with a giant splenic epidermoid cyst. A 26-year-old woman presented to our hospital with the major complaint of a feeling of abdominal fullness. Prior to surgery, an ultrasound-guided splenic cyst puncture was conducted for diagnostic purposes as well as to reduce the size of the cyst. The carbohydrate antigen 19-9 (CA 19-9) level was found to be elevated in the cystic contents and in the serum. Under laparoscopic guidance, the splenic vessels were ligated using a device for extracorporeal ligation, then divided. After the resected spleen had been placed in a retrieval bag, it was delivered out of the abdominal cavity without fragmentation. Following surgery, the patient's serum CA 19-9 level returned to normal. Splenic epidermoid cysts are most often encountered in young women, and laparoscopic surgery to remove cysts of this type is both minimally invasive and excellent from a cosmetic standpoint. Thus, laparoscopic surgery should be considered as the method of choice for the majority of patients diagnosed with a splenic epidermoid cyst.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/20. pachyonychia congenita tarda.A 42-year-old man presented with painful toenails which were overcurved transversely and onycholytic. Examination revealed that all toenails, the thumbs and index fingers were similarly affected. In addition, he had a small area of leukokeratosis in the mouth, epidermal cysts of the scrotal skin and a small area of hyperkeratosis on the ulnar borders of his hands. His characteristic nail changes began in the great toenails at the age of 20 years. After renal transplantation at age 39, the other nails changed and he developed the features described above. His sister has overcurvature of the fifth toenails. A diagnosis of pachyonychia congenita tarda was made. His case is compared with 14 other reported cases of this rare syndrome.- - - - - - - - - - ranking = 2.2708091378216keywords = mouth (Clic here for more details about this article) |
3/20. Ruptured epidermoid cyst and haematoma of spleen: a diagnostic clue of high levels of serum carcinoembryonic antigen, carbohydrate antigen 19-9 and Sialyl Lewis x.Splenic epidermoid cyst is a rare disease and that with haematoma is even more rare. The case of epidermoid cyst of the spleen is described, in a 36-year-old Japanese female, manifesting as left hypochondralgia and rupture of the cyst. Clinical features were splenic lesion 14 cm in diameter and consisting of round-hypovascular and crescent-hypervascular sublesions. Extravasation of cystic fluid was detected in abdominal cavity Preoperative diagnosis was difficult due to such uncommon features, however high levels of serum tumour markers (carcinoembryonic antigen, carbohydrate antigen 19-9, Sialyl Lewis x) strongly suggested epidermoid cyst. Laparotomic splenectomy and cholecystectomy were performed for splenic lesion and gallstones, and serum tumour markers decreased following surgery. Pathological diagnosis of the round-hypovascular lesion was epidermoid cyst and crescent-hypervascular lesion was haemorrhage (haematoma).- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
4/20. Sublingual epidermoid cyst.Dermoid and epidermoid cysts are developmental pathologies that occur in the head and neck with an incidence ranging from 1.6 to 6.9%, and they represent less than 0.01% of all oral cavity cysts.Our purpose is to report a case of sublingual epidermoid cyst of the floor of the mouth. We studied and operated on an 18-year-old white male patient showing a large swelling of oral floor. His main symptoms were difficulty breathing, swallowing, and speaking. At his birth the patient's tongue was adherent to the floor of the mouth. His father had the same problem at birth. Both father and son underwent surgical separation of tongue, during the post-neonatal period.After the surgical removal of the swelling, under general anesthesia, all the patient's symptoms were missed. Histological examination of the mass confirmed the diagnosis of an epidermoid cyst. No relapse of the lesion was present in ten months of follow-up. Many theories are proposed on the etiology of the epidermoid and dermoid cyst. In this case a traumatic event can be found, such as an operation of the tongue in neonatal age. However a multifactorial origin must be assumed for justifying the fact that the patient's father did not develop a dermoid cyst although he had the same problem of an adherent tongue and was operated on.- - - - - - - - - - ranking = 22.449175789455keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
5/20. Multiple palmar epidermoid cysts.Implantation of epidermal fragments into the dermis has been pointed out as the cause of common epidermal cysts. However, some palmoplantar epidermoid cysts have been reported to be caused by human papillomavirus (HPV) infection or to be derived from eccrine ducts. A 65-year-old left-handed woman presented with extraordinary multiple epidermoid cysts on the palm and volar aspect of the fingers of her left hand. HPV infection was not detected by immunohistochemistry, in situ hybridization and polymerase chain reaction. Histological investigation revealed syringeal structures within the cyst wall and in the cyst cavity. carcinoembryonic antigen was observed in these syringeal structures but was not specifically stained in the cyst wall cells by immunohistochemistry. The cytokeratin composition of the cyst wall cells was similar to that of the nonadnexal epidermis.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
6/20. Plunging congenital epidermoid cyst of the oral cavity.Epidermoid cysts are rare lesions in the oral cavity. They usually present early in life and are confined to one anatomical area. Simple excision is all that is needed. However, they may present late in life and be large in size, making their excision a real challenge. We present a case of congenital epidermoid cyst of the sublingual space that presented late, at the age of 17 years, after it plunged into the submental area. The presentation of the patient and the surgical approach are discussed.- - - - - - - - - - ranking = 89.537787569061keywords = oral cavity, cavity (Clic here for more details about this article) |
7/20. Lingual epidermoid cyst: case report in an infant.The purpose of this article was to present a rare case of epidermoid cyst on the ventral region of the tongue in a 15-month-old child. During clinical examination, a sessile, yellowish lesion measuring approximately 0.5 cm was noticed. The lesion had existed since the child's birth and was causing discomfort due to friction of the tongue against the alveolar ridge during mastication. The chosen treatment was total removal of the lesion. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (1) a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (2) connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/20. Epidermoid cyst in an intrapancreatic accessory spleen: a case report.Ectopic splenic tissue in the abdominal cavity is a common entity, with a reported incidence of 10% in the general population. However, an intrapancreatic accessory spleen is a rare disease, and moreover cyst formation in it is exceedingly rare. A 58-year-old woman with a 25-mm multilocular cyst in the tail of the pancreas detected incidentally by ultrasonography was admitted for further evaluation. Because malignancy could not be ruled out, a spleen-preserving distal pancreatectomy was performed. The cut surface of the surgical specimen showed a multilocular cyst surrounded by brown solid tissue resembling normal spleen. Pathological examination revealed it was stratified squamous epithelium and was surrounded by splenic tissue. The final pathological diagnosis was epidermoid cyst in an accessory spleen in the pancreas. This cyst has no characteristic features on diagnostic imaging. Consequently, it is not possible to make a definite preoperative diagnosis in most cases. Epidermoid cyst in intrapancreatic splenic tissue is another lesion to be considered in the differential diagnosis of pancreatic tail tumors.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/20. Epidermoid cyst of the brain stem symptomatic in childhood.BACKGROUND: Epidermoid cysts may remain asymptomatic for a long period of time due to their slowly growing pattern corresponding with the normal human skin turnover time and due to soft and light cyst content. They do not cause compression of neural and vascular structures initially that is why almost all of the cases in the literature are diagnosed during adulthood. methods: We report here an epidermoid cyst in childhood, which was located in the medulla oblongata, unusually and atypically with liquefied cyst content. The liquefaction may occur due to an intrauterine or early childhood infection. The reported case also suffered previously a severe respiratory infection. Although the cyst is located in and around a highly eloquent neural area, plasticity of the brain stem prevented neurological deterioration due to this very slow growing extraaxial mass lesion. The ordinary cyst content found in the center of the cyst cavity during the operation suggested that the same ordinary material, which was previously at the periphery, ran to get liquefied in time. CONCLUSION: We suggest that the symptoms of this present case appeared very early due to liquefaction of the cyst content with compression and displacement of the brain stem caudally. The recent infection process may predispose the pathological condition.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/20. Coexistence of lymphoepithelial and epidermoid cysts on the floor of the mouth: report of a case.Lymphoepithelial and epidermoid cysts in the oral cavity are uncommon. The coexistence of lymphoepithelial and epidermoid cysts in the oral cavity is extremely rare. Only one case of lymphoepithelial cyst associated with two epidermoid cysts on the floor of the mouth has been reported in the literature and the present report describes a second case where a lymphoepithelial cyst coexisted with an epidermoid cyst on the floor of the mouth. It is likely an accidental trauma that was accompanied by inflammation produced the development of implantation-keratinizing epidermoid and lymphoepithelial cysts.- - - - - - - - - - ranking = 49.439969854554keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
