Leiomyoma in a female urethral diverticulum

Neoplasms arising within urethral diverticula are rare. It is important to know if a diverticulum is fi lled by tumor, but traditional diagnostic methods, such as voiding cystourethrography, cannot detect a tumor or diverticulum, as in our case. We report an unusual case of leiomyoma developing in a female urethra diverticulum and review the literature

Total resection of inferiorly located sacral chordoma with posterior only approach: case report and review of the literature

Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1-4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. The treatment of primary sacral tumors represents a challenge because of a large tumor mass at presentation and a hemorrhage risk in surgery. Sacral tumors may present a difficult problem to the surgeon who desires to obtain a clear margin of excision. Using the retrorectal fat tissue as a cleavage line in the posterior approach guides the neurosurgeon to resect the tumor totally and reduce the hemorrhage in sacral chordomas. In this case report, we tried to discuss the advantages of using of retrorectal fat tissue as a cleavage line in sacral chordomas under the literature.Kordoma ektodermal kaynaklı primer sakral neoplazmdır ve tüm primer kemik tümörlerinin %1-4’ünü oluşturur. Genellikle serebrospinal aksın orta hattında bulunurlar ve çoğunlukla yerleşim yerleri sfenoklival bölge ve sakrumdur. Primer sakral tümörlerin tedavisi; ilk ortaya çıktıklarında büyük bir kitle oluşturmuş olmaları ve cerrahide kanama riskleri nedeniyle çözülmesi gereken bir sorun olarak durmaktadır. Sakral tümörler, net bir eksizyon sınırı sağlamak isteyen cerrahlar için zorlu bir problem oluşturur. Posterior yaklaşımda retrorektal yağ dokusunun klavaj hattı olarak kullanılması; beyin cerrahına tümörün tümüyle rezeke edilmesi için yol gösterir ve sakral kordomalarda kanamayı azaltır. Bu olgu sunumunda, sakral kordomalarda retrorektal yağ dokusunun klavaj hattı olarak kullanılmasının yararlarını literatür eşliğinde tartışmak istedik

Recurrent renal giant leiomyosarcoma

Primary renal leiomyosarcomas are rare, aggressive tumors. They constitute 1-2% of adult malignant renal tumors. Although leiomyosarcomas are the most common histological type (50-60%) of renal sarcomas, information on renal leiomyosarcoma is limited. Local or systemic recurrences are common. The radiological appearance of renal leiomyosarcomas is not specific, therefore renal leiomyosarcoma cannot be distinguished from renal cell carcinoma by imaging methods in all patients. A 74-year-old female patient presented to our clinic complaining of a palpable mass on the right side of her abdomen in November 2012. The abdominal magnetic resonance imaging revealed a mass, 25 x 24 x 23 cm in size. Her past medical history revealed that she has undergone right radical nephrectomy in 2007, due to a 11 x 12 x 13 cm renal mass that was then reported as renal cell carcinoma on abdominal magnetic resonance imaging, but the pathological diagnosis was low-grade renal leiomyosarcoma. The most recent follow-up of the patient was in 2011, with no signs of local recurrence or distant metastases within this four-year period. The patient underwent laparotomy on November 2012, and a 35 cm retroperitoneal mass was excised. The pathological examination of the mass was reported as high-grade leiomyosarcoma. The formation of this giant retroperitoneal mass in 1 year can be explained by the transformation of the lesion’s pathology from low-grade to a high-grade tumor

Ipsilateral Lymphatic and Venous Malformations Affecting the Midface Area

A 22-year-old woman presented with progressive swelling of the nasal conjunctiva in the left eye. Anterior segment examination revealed a diffuse cystic appearance to the inferonasal bulbar conjunctiva and plica semilunaris. Anterior segment swept-source optical coherence tomography (OCT) revealed clear hyporeflective spaces demarcated by hyperreflective septae in the affected conjunctiva, consistent with the diagnosis of lymphatic malformation (LM). Magnetic resonance imaging revealed a well circumscribed intraconal mass located inferonasally in the left orbit. Systemic examination revealed a lesion similar to LM on the left hard palate. The left conjunctival mass was excised subtotally. Subsequently, a transconjunctival anterior orbitotomy was performed and the left orbital mass was completely removed intact. Histopathologically, the conjunctival mass was diagnosed as LM and the orbital mass as venous malformation (VM). This case represents a rare coexistence of histopathologically proven conjunctival LM and orbital VM as well as a presumed LM of the hard palate, all 3 lesions occurring in the ipsilateral midface area

Malignant Transformation of Dental Material-induced Oral Lichenoid Contact Reaction: A Case Report Describing Outcomes After Amalgam Removal

Oral lichen planus (OLP) is a chronic immune-mediated dermatosis of unknown origin. Considered as one of the most common diseases of the oral mucosa, OLP has been subject of intense interest since its first identification as a premalignant condition. Oral lichenoid contact reactions (OLCRs) are distinct analogs of OLP lesions, in that they are nearly indistinguishable from OLP both clinically and histologically. There is an on-going debate about whether the underlying condition causing OLP-induced malignant oral squamous cell carcinoma is OLP or OLCR. Even currently, a considerable number of patients with OLCR are diagnosed and managed as OLP without searching for specific causative agents. Dental restorative materials are one of the most common inducers of OLCR. Here, we describe a case with dental material-induced OLCR, who had previously undergone marginal mandibulectomy and neck dissection with a diagnosis of invasive well differentiated squamous cell carcinoma associated with OLP. We emphasize the need for investigation of possible etiological factors in every case of OLP or OLCR, as a basal patch test may completely change the course of the disease

Chronic Sclerosing Sialadenitis (Küttner's tumour) of the Parotid Gland

Chronic sclerosing sialadenitis is a chronic inflammatory salivary gland disease. Küttner reported 4 cases of submandibular gland lesions for the first time in 1896. Chronic sclerosing sialadenitis is a very rare inflammatory lesion of the parotid gland and cannot be easily distinguished from salivary malignant masses. We reported a 28-year-old male with a painful parotid tumour, which grew slowly for 4 years
