OCLC Number/Unique Identifier: 7964734669

Aim: The aim of this study was to determine the sensitivity of the tumor markers and diagnostic methods used in the preoperative period for dermoid cysts, the most common benign neoplasm of the ovary. Material and Methods: 136 patients who were operated for any reason and reported as ovarian dermoid cyst in the Department of Obstetrics and Gynecology, Ankara Atatürk Training and Research Hospital between January 2004 and September 2005 were included in the study. The medical records of the cases were obtained retrospectively from Ankara-Atatürk Training and Research Hospital, HIS, archive files and patient numbers where necessary. Results: In the preoperative period, 119 patients underwent ultrasonographic examination, 33 underwent Computed Tomography, and 17 underwent Magnetic Resonance Imaging.10 of the cases only underwent CT, while 3 of the cases underwent only MRI 22 of them underwent both USG and CT, USG and MRI were performed on 13 cases and only 1 case underwent all three of the imaging methods. Tumor markers were CEA, CA 125, CA 19-9, CA 15-3 and AFP. Conclusions: The reviews of ultrasonography and / or computed tomography and / or magnetic resonance imaging (n = 132) revealed that 103 of the cases were put into operation and the sensitivity of the preoperative screening methods were calculated to be 75.5%. The sensitivity of the tumor marker CA 19-9 was calculated to be 31%.

Recurrent Mucoepidermoid Carcinoma of Parotid with Facial Tics - Report of an unusual case

Published on: 16th June, 2017

OCLC Number/Unique Identifier: 7317651487

We report an interesting case of a 21 year old male who presented with recurrent mucoepidermoid carcinoma of parotid with facial nerve involvement as facial tics. Intraoperatively, the tumour was noted to be firm, irregular and adherent to the underlying structures. The patient underwent extended total parotidectomy, division of buccal branch of facial nerve, selective neck dissection with cervical local rotational flap repair and post-operative radiotherapy. This presentation of Mucoepidermoid carcinoma with involvement of facial nerve as facial tics is one of the rare unique reported cases.

A rare presentation of orbital dermoid: A case study

Published on: 10th August, 2021

OCLC Number/Unique Identifier: 9168714793

Introduction: A dermoid cyst is a developmental choristoma lined with epithelium and filled with keratinized material arising from ectodermal rests pinched off at suture lines. These are the most common orbital tumors in childhood. They are categorized into superficial and deep. Superficial orbital dermoid tumors usually occur in the area of the lateral brow adjacent to the frontozygomatic suture. Infrequently a tumor may be encountered in the medial canthal area [1], which is the second most common site of orbital dermoids. We report a case where a swelling presented in the medial canthal area without involving the lacrimal system. Case report: A 43 year old lady presented with complaint of swelling near the (RE; Right eye) since 2 years duration. She presented with a solitary 1.5 cm x 1 cm ovoid, non-tender, non-pulsatile, firm, non-compressible mobile swelling with smooth surface over the medial canthus of right eye. (MRI; Magnetic Resonance Imaging) brain and orbit showed right periorbital extraconal lesion and the (FNAC; Fine Needle Aspiration Cytology) suggested of Dermoid Cyst. RE canthal dermoid cyst excision was done under Local Anasthesia. Conclusion: Complete surgical excision in to be treatment of choice for dermoids. Since medial canthal mass can involve the lacrimal system, it becomes necessary to perform preoperative assessments using (CT; Computed Tomography), MRI or dacryocystography while planning the surgical approach. Silicone intubation at the beginning of the surgery is an easy and effective way of identifying canaliculi and of preventing canalicular laceration during dermoid excision if the lacrimal system is found to be involved.

Dermoid Cyst of the Mesentery of the Jejunum Following Appendectomy: A Clinical Case

Published on: 7th November, 2023

Mesenteric cysts and cystic mesenteric tumors are very rare abdominal growths. They may be localized all over the mesentery, from the duodenum to the rectum, however, they are mostly found in the ileum and right colon mesentery. There are several classifications of these formations, among which the one based on histopathologic features including 6 groups has been most commonly used: 1) cysts of lymphatic origin--lymphatic (hilar cysts) and lymphangiomas; 2) cysts of mesothelial origin--benign or malignant mesothelial cysts; 3) enteric cysts; 4) cysts of urogenital origin; 5) dermoid cysts; and 6) pseudocysts-infectious or traumatic etiology.A dermoid cyst is a benign, epithelial-lined cavitary lesion composed of ectoderm and mesoderm that can arise anywhere in the body, with a tendency to develop in midline structures.In 20% - 45% of cases, accompanying diseases that were not previously clinically manifested can be diagnosed during emergency interventions, requiring additional surgical interventions for their correction.The aim of the study is to demonstrate the successful treatment experience of a dermoid cyst of the mesentery of the jejunum, detected after traditional appendectomy.Clinical case:  A mother brought her 9-year-old son, V., to the emergency department of the Kursk Regional Children’s Clinical Hospital with complaints of moderate-intensity pain in the right iliac region, multiple episodes of vomiting, and fever. Ultrasound features indicative of destructive appendicitis and peritonitis. In an emergency situation, after preoperative preparation, a traditional appendectomy was performed under intravenous anesthesia, using the Volkovich-Dyakonov approach. The postoperative period was uneventful. Moderate infiltration was observed on the control abdominal ultrasound examination, in the intestine (presumably the small intestine) in the right half of the abdominal cavity, with a solid formation measuring 27*33 mm, producing a dense acoustic shadow. On the 7th day after the initial intervention, a revision of the abdominal organs was performed. The loop of the jejunum with the formation was brought out into the wound. The capsule above the formation was dissected: the formation of bone density, when the capsule is separated, resembles a fecal stone in structure, considering the localization - a dermoid cyst. Step-by-step enucleation of the cyst was performed. The postoperative wound was tightly sutured in layers.
