Sarcomas of the Larynx: One Institution's Experience and Treatment Protocol Analyses.

Soft tissue sarcomas in the head and neck are rare malignancies. They occur in this area in less than 1% of all malignant tumors. Some authors have described the development of sarcoma from the mesenchymal tissue in the larynx.

Primary renal well-differentiated neuroendocrine tumour (carcinoid): next-generation sequencing study of 11 cases.

Aims: Primary renal well-differentiated neuroendocrine tumour (NET) (hereafter referred to as renal NET) is rare, with ~100 cases having been reported in the literature. There are also limited data on the molecular-genetic background of primary renal NETs.

Methods And Results: We analysed 11 renal NETs by using next-generation sequencing (NGS) to identify characteristic genetic aberrations.

[Can robotic rectal cancer surgery improve quality of total mesorectal excision?].

Introduction: The introduction of total mesorectal excision (TME) in the 1980s was pivotal in the surgical treatment for rectal carcinoma (RC). Routinely applied TME led to a significant reduction in the incidence of local recurrences. The purpose of our paper is to present the results of our non-randomized study comparing prospectively acquired data from radical resection / rectal extirpation using classic open access, laparoscopy and da Vinci robotic system.

Sebaceous adenoma arising in mature cystic teratoma of the ovary. Case report.

We report the case of a 44-year-old female with sebaceous adenoma arising in mature cystic teratoma of the ovary. The patient had a tumor in the left ovary; 125 x 90 x 70 mm. Microscopically, the tumor consisted of structures typical of dermoid cysts.
