Bilateral Schneiderian (sinonasal) papilloma: An uncommon rare entity

Sinonasal papilloma is a benign surface mucosal neoplasm with variable growth pattern and cytological features. It is a rare benign tumor with tendency to recur and also malignant transformation. The most common sites of inverting papillomata are lateral nasal wall and middle meatus and are usually unilateral. Rarely Bilateral disease can occur, which may be due to direct extension of the tumour, but can also occur as two distinct lesions. The etiology still remains unclear, eventhough the morphology and clinical behavior of this lesion has been well described. Here we report a case of recurrent bilateral nasal polyposis, histologically diagnosed as Inverted sinonasal papilloma, which is a rare entity.

Abstract Introduction: Renal hemangioblastoma (RH) is a very rare benign tumor. Hemangioblastoma most commonly occur in the central nervous system (CNS) and only few cases of RH have been reported as they occur most commonly as asymptomatic masses found incidentally. Mixed Mullerian Tumor (MMT) of the uterus is a rarer and aggressive form of uterine malignancy. The detection of two primary rare tumors incidentally is a rare entity. Case presentation: A 50 years female presented with abnormal uterine bleeding which on endometrial sampling was diagnosed as a rare variety of endometrial cancer i.e., MMT or uterine carcinosarcoma. On preoperative imaging, a renal mass was also detected which was highly vascular and was mimicking Renal Cell Carcinoma (RCC). Fine needle aspiration cytology (FNAC) was done from the renal mass to differentiate between RCC and metastasis but it showed only blood cells. Patient underwent staging laparotomy for endometrial cancer and frozen section examination of the renal mass which was inconclusive with few atypical cells and thus patient underwent radical nephrectomy too. Histopathological examination revealed it to be a RH which is a very rare benign tumor. Discussion: RH is a rare benign tumor which doesn’t require any treatment in majority of the patients. Only 26 cases of RH outside the CNS have been reported till date. MMT is a rare aggressive uterine tumor with an incidence of 1-2 % of all uterine neoplasms, which metastasizes early and thus early identification and treatment is the key. RH needs to be differentiated from RCC to avoid over treatment. Morphological findings are similar in both, preoperative FNAC, PET scan and intraoperative frozen section can be utilized to differentiate in between two in well circumcised tumors and in high suspicion. Occurrence of renal mass as an incidental finding in the preoperative work up of uterine malignancy directed us to the differentials of metastasis or another histologically distinct primary tumor. The presence of two rare primary tumors i.e., RH and MMT in the same patient which are unrelated is a rare entity.

Abstract Introduction Renal hemangioblastoma (RH) is a very rare benign tumor. Hemangioblastoma most commonly occur in the central nervous system (CNS) and only few cases of RH have been reported in literature. They occur most commonly as asymptomatic masses found incidentally. Mixed Mullerian Tumor (MMT) of the uterus is a rarer and aggressive form of uterine malignancy. The detection of two primary rare tumors incidentally is a rare entity. Case presentation A 50 years female patient presented with abnormal uterine bleeding which on endometrial sampling was diagnosed as a rare variety of endometrial cancer i.e., MMT or uterine carcinosarcoma. On preoperative Magnetic resonance imaging (MRI), a renal mass was also detected which was highly vascular and was mimicking Renal Cell Carcinoma (RCC). Fine needle aspiration cytology (FNAC) was done from the renal mass to differentiate between RCC and metastasis but it showed only blood cells. Patient underwent staging laparotomy for endometrial cancer and frozen section examination of the renal mass. Frozen section report was inconclusive with few atypical cells and thus patient underwent radical nephrectomy too. Histopathological examination revealed it to be a RH which is a very rare benign tumor. Discussion Only 14 cases of RH outside the CNS have been reported till date. Occurrence of renal mass as an incidental finding in the preoperative work up of uterine malignancy directed us to the differentials of metastasis or another histologically distinct primary tumor. RH may mimic RCC radiologically. To correctly diagnose RH is important because sporadic RH does not require further treatment and the prognosis is much better than that of RCC. MMT which compromise 1-2% of all uterine neoplasms have higher chance of metastasis than endometroid variety. Conclusion Renal hemangioblastoma is a rare benign tumor which doesn’t require any treatment in majority of the patients. Mixed Mullerian tumor is a rare aggressive uterine tumor which metastasizes early, henceforth early identification and treatment is the key. RH needs to be differentiated from RCC to avoid over treatment. Morphological findings are similar in both, preoperative FNAC, PET scan and intraoperative frozen section can be utilized to differentiate in between two in well circumcised tumors and in high suspicion. The presence of two rare primary tumors i.e., RH and MMT in the same patient which are unrelated is a rare entity.

Leiomyoma is a benign tumor showing smooth muscle differentiation. Leiomyoma in the nasal cavity is a rare entity which can present with common nasal symptoms. We report a case of 19 years old male patient with nasal leiomyoma. The patient presented with recurrent episodes of nasal obstruction and epistaxis. On nasoendoscopy, there was a single grayish polypoidal mass in the right middle meatus which bled on touch. CT-scan of nose and paranasal sinus showed homogenous opacity indistinguishable from the right middle turbinate. The mass was excised endoscopically. There is no recurrence a year after the endoscopic excision of the nasal leiomyoma. Nasal leiomyoma carries a good prognosis after complete excision.Key words: endoscopic excision, leiomyoma, nasal cavity

Rare Benign Tumor

We report a rare case of a parotid oncocytoma in a 63-year-old woman. It is a rare benign tumor accounting for less than 1.5% of all salivary gland tumors. It is known as the parotid mitochondrioma because it is made of cells rich in mitochondria with granular cytoplasm. It is a rare entity poorly documented in the literature, and there are no pathognomonicsymptoms or imaging, which makes the diagnosis of this tumor challenging.Surgery is the main treatment, and the diagnosis is confirmed by the histological study of the specimen. Through this observation, and in light of the literature, we will underline the anatomoclinical and radiological peculiarities of this tumor, to induce clinicians to consider this histological type.

Lingual osseous choristoma is a rare benign tumor consisting of normal matured bone tissue. It was first reported in 1913, and less than 100 cases of lingual osseous choristomas, mainly in their twenties and thirties, have been reported in the English literature until now. Here, we report an additional case of lingual osseous choristoma, in an elderly patient, that was incidentally removed by coughing and cured without additional interventions. An 89-year-old male patient was referred to our department for an evaluation of chronic cough. When we examined his oral cavity and pharynx, he expectorated a 10 -mm mass which was histologically diagnosed as an osseous choristoma. We confirmed the well-defined, rounded, high-density mass with a tiny pedicle on the base of the tongue in previous cervical spine CT images. No signs of recurrence were found during the 15-month follow-up examination. Our case serves as a reminder of this rare entity in the diagnosis of tongue masses of the elderly.

AbstractCutaneous xanthogranuloma is a rare benign tumor and both adults and children could be affected. Head and neck area of the human body is the most commonly affected one which often poses a serious reconstructive challenge for the plastic surgeon who is in charge of removing the lesion. We report on a clinical case of an adult female patient who presented with cutaneous xanthogranuloma of the upper lip, involving the subnasal area. Both diagnosis and surgical treatment were difficult, considering the clinical behavior and location of the tumor. An innovative surgical approach going out of the dogmas of plastic surgery was applied and an excellent result was achieved.

Background: Hemolymphangioma is a rare benign tumor. To the best of our knowledge, there were only 10 reports of this tumor of the pancreas until March 2018. Case Report: Here, we reported a large invasive hemolymphangioma of the pancreas in a young woman with a complaint of abdominal distension and an epigastric mass about 3 weeks. She was found to have a huge multilocular cystic tumor at the neck and body of pancreas on computed tomography. She was eventually diagnosed with hemolymphangioma of the pancreas after operation. After 2 years of follow-up, there was no signs of recurrence. Conclusion: From our case and literature, we can conclude that hemolymphangioma of the pancreas is uncommon benign tumor, and it is hard to make an accurate diagnosis preoperatively. Radical surgical resection should be performed whenever possible. The prognosis of this disease seems good.

Testicular fibroma of gonadal stromal origin is a rare benign tumor of testis, which usually presents as a slow growing testicular mass. Intratesticular fibroma of gonadal stromal origin, with or without minor sex cord elements, must be considered, analogous to similar tumors in ovary, as a benign tumor. Until now, only 25 cases of testicular fibroma have been reported in the literature. We reported a case of testicular fibroma in a 20 years male who presented with painless right testicular enlargement since two years. Ultrasonography (USG) showed heterogeneous mass in right scrotum suggestive of testicular malignancy. Right orchidectomy was done. Histopathological diagnosis was testicular fibroma, which was confirmed by immunohistochemistry.

Accessory Parotid Gland

Diagnosis of mid-cheek mass has always been a diagnostic dilemma for clinicians. The incidence of the accessory parotid gland (APG) has been well documented in the literature. However, a diverse spectrum of pathologies can arise from this accessory parotid tissue. Basal cell adenoma is a rare benign tumor that predominantly affects the parotid gland. Its occurrence in the accessory parotid gland has been documented in 9 cases till date. Surgical approaches for the management of such APG lesions have been in debate. This report documents a case of Basal Cell Adenoma arising in accessory parotid tissue in a 55-year-old woman who was treated by transoral excision. This paper also reviews previously documented cases of all APG lesions and attempts to elucidate the rationale for selecting an appropriate surgical approach.
