Paragangliomas can be found from the skull base to the sacrum. Sinonasal paragangliomas are infrequent. A 16-year-old female reported spontaneous discrete bilateral epistaxis once a month beginning when she was 3 years of age. Computed tomography showed an expansive hypervascular mass occupying the right nasal cavity and nasopharynx. Sinonasal paragangliomas usually occur in middle-aged women. Radiologic investigation is essential for the diagnosis of sinonasal paragangliomas and evaluating extension of the lesion. Endoscopic and conventional approaches are effective, and preoperative embolization is paramount for reducing bleeding risk. Histopathological features cannot differentiate benign from malignant paragangliomas, and since metastasis may eventually occur, follow-up must be carried out for a long period of time.

Cranial Injury

A ten-month old, male Black and Tan Coonhound dog was referred with ocular bleeding due to gunshot injury. His mental state was normal. A computed tomography revealed that the bullet was planted in the left cranium. It was presumed that the trajectory of the bullet penetrated from the right medial angle of the eye to the orbit, and changed its track to caudo-dorsal by penetrating the cranium, ending up at the left cranium. The bullet was removed by lateral rostrotentorial craniectomy. No complications were observed during a one-year follow-up except the blindness in the right eye. This is a rare case of gunshot-induced traumatic brain injury featuring a bullet which went through the orbit into the cranium. The damaged frontal lobe seemed to show no neurological signs at the time of first examination in this case. In conclusion, a less aggressive surgical approach is recommended to remove bullets when they are accessible.

Liposarcoma is a common soft tissue sarcoma. However, its occurrence in pancreas or stomach is extremely rare. In the present study, a rare case of a 55-year-old female with sclerosing liposarcoma in pancreas and stomach is presented.  Ultrasound, magnetic resonance imaging and computed tomography examinations were performed, which revealed a pancreatic mass. Subsequently, the patient underwent surgical resection of the tail of the pancreas and spleen and partial resection of stomach following the identification of a second mass. After surgery, the patient received no adjuvant treatment. Subsequent to 3 years of clinical follow up, the patient remains alive without recurrence or distant metastasis so far. As far as we know, this is the first reported case of sclerosing liposarcoma involving pancreas and stomach.

Transnasal Endoscopic Surgery

AbstractA case of angiofibroma limited to the right posterior nasal cavity, nasopharynx, and pterygopalatine fossa was operated upon transnasally under endoscopic control. The tumour was completely excised without complications. Endoscopic follow-up for the next two years and contrast computed tomography (CT) excluded any residual tumour or recurrence. The advantages, limitations and possible complications of this approach are discussed. It seems that in limited lesions of angiofibroma, the option of a transnasal endoscopic approach could be cautiously considered by experienced surgeons.

Pleomorphic adenomas arising in the nasal cavity are extremely uncommon, despite the large numbers of minor mucous and serous glands in the region. We present a rare case of a pleomorphic adenoma arising from the right nasal vestibule in a 65-year-old man complained of right nasal obstruction for 6 months. Anterior rhinoscopy showed a reddish, firm, polypoid mass in right nasal cavity which is free from the nasal septum and from the inferior tubinate but it was attached to the nasal vestibule. Flexible nasal endoscopy showed no extension of the mass towards the posterior choana or nasopharynx. The mass was completely excised from the nasal vestibule through intranasal approach and sent for histology which confirmed a pleomorphic adenoma with a predominant stromal component. The main treatment modality is surgical resection with histological clear margins. Recurrences and evolution to malignancy are not frequent, but long tern follow-up is recommended. In our case, the patient demonstrated satisfactory cosmetic results with no evidence of recurrence. Bangladesh J Otorhinolaryngol; April 2017; 23(1): 88-91

AbstractThe use of an ileal segment is a standard method for urinary diversion after radical cystectomy. Unfortunately, utilization of this method can lead to numerous surgical and metabolic complications. This study aimed to assess the tissue-engineered artificial conduit for urinary diversion in a porcine model. Tissue-engineered tubular polypropylene mesh scaffolds were used for the right ureter incontinent urostomy model. Eighteen male pigs were divided into three equal groups: Group 1 (control ureterocutaneostomy), Group 2 (the right ureter-artificial conduit-skin anastomoses), and Group 3 (4 weeks before urostomy reconstruction, the artificial conduit was implanted between abdomen muscles). Follow-up was 6 months. Computed tomography, ultrasound examination, and pyelogram were used to confirm the patency of created diversions. Morphological and histological analyses were used to evaluate the tissue-engineered urinary diversion. All animals survived the experimental procedures and follow-up. The longest average patency was observed in the 3rd Group (15.8 weeks) compared to the 2nd Group (10 weeks) and the 1st Group (5.8 weeks). The implant’s remnants created a retroperitoneal post-inflammation tunnel confirmed by computed tomography and histological evaluation, which constitutes urostomy. The simultaneous urinary diversion using a tissue-engineered scaffold connected directly with the skin is inappropriate for clinical application.

Renal cell cancer metastases without evidence of a primary tumor are extremely rare. These variants are usually showed as a spontaneous description of single clinical cases. Aim.This contribution is a clinical follow-up of synchronous renal cell cancer metastases of unknown primary site. Results.A 52-year-old patient U. with a history of increased blood pressure, up to 170/100 mmHg for the last 5 years, who had undergone many instrumental examinations, including ultrasound examination, because of this disease. The computed tomography of the abdomen showed a 4975 mm heterogeneous tumor in the right adrenal gland in October 2017. The combined positron emission and X-ray computed tomography showed a 795441 mm mass in the right adrenal gland, associated with elevated fluorodeoxyglucose metabolic activity SUVmax 7.25. Focal accumulation of the radiopharmaceutical SUVmax 4.31 in a 171124 mm mass was detected in the space of bifurcation in the mediastinum. The lytic lesion (1015 mm) was found in right superior L3 articular process. The patient underwent retroperitoneoscopic adrenalectomy and thoracoscopic removal of mediastinal tumor in November 2017 because of the oligometastatic nature of the process. The histological study identified clear-cell carcinoma with areas of papillary structure in the right adrenal gland. The immunohistochemical study showed carcinoma cells intensively expressing CD10, and some other cells RCC. The immune phenotype of the tumor was identified as clear-cell renal cell carcinoma. The immunohistological and immunohistochemical analysis reviled the metastases of the same variant of renal cell carcinoma in one of 9 lymph nodes. The patient was treated with pazopanib. The primary renal tumor was not detected during the dynamic observation, including the application of annual combined positron emission and X-ray computed tomography. The patient is alive without disease progression with a follow-up of 32 months. Conclusion.Metastases of clear-cell renal cell carcinoma, including adrenal gland, without evidence of a primary site are extremely rare. The main method of treatment is a combination of surgery and targeted therapy, providing long-term local control of the course of the disease.

<p>Primary mucosal melanoma of the nasal cavity and paranasal sinuses is a very aggressive and rare disease with only about 0.5 % of malignant melanoma arising from the nasal cavity. There are only few reports from India. We report a rare case of sino-nasal mucosal malignant melanoma in a 58 years old female who presented with blackish coloured sino-nasal mass involving right nasal cavity, spontaneous and recurrent epistaxis and obliteration of the right naso-labial fold with occasional pain in the past 10 months. Contrast enhanced computed tomography scan showed a heterogenous mass involving right nasal cavity, right maxillary antrum and right ethmoidal area. A positron emission tomography computed tomography was also done which showed increased uptake in the region mentioned above. Initial biopsy, the mass was diagnosed as malignant melanoma. Total maxillectomy was performed with plan of post-operative radiotherapy.</p>

Servelle Martorelle Syndrome is a congenital vascular malformation associated with soft tissue hypertrophy and bony hypoplasia. This rarely involves whole of an extremity, with involvement of part of limbs reported in literature. We present a case of a twelve year boy who presented to the Department of Plastic Surgery SGPGIMS in April 2011 ,with history of circumferential soft tissue hypertrophy involving whole of left upper limb, scapular region and axilla since birth. The entire left upper limb length was lesser than the right upper limb. Hence this is a very rare case of Servelle Martorelle Syndrome having extensive limb involvement at a very young age. Highlighted is the role of conservative treatment and close follow-up to understand the natural history of the diseases, with prompt treatment of complications.
