Objective:       To report a case of extragnathic sinonasal ameloblastoma and discuss its clinical features, approach to diagnosis, pathology, and management.   Methods: Study Design:             Case report Setting:                       Tertiary government university hospital Subject:                      One   Results:  A 40-year-old female consulted for a rapidly enlarging right intranasal mass of 4 months duration associated with recurrent profuse epistaxis and nasal obstruction.  Previous specimens of the mass were histopathologically interpreted as ameloblastoma versus craniopharyngioma.  Examination revealed a pink, fleshy, smooth right intranasal mass with associated nasomaxillary bulge and supero-lateral displacement of the right eye.  Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the nasal cavity and paranasal sinuses demonstrated a soft-tissue density occupying the entire nasal cavity with erosion but no invasion of the maxillary sinus and no intracranial extension despite erosion of the skull base.  The mass was completely excised via lateral rhinotomy and the final histopathologic diagnosis was ameloblastoma.   Conclusion:    Extragnathic sinonasal ameloblastoma is a benign but locally aggressive variant of ameloblastoma involving the nasal cavity and/or paranasal sinuses often mimicking malignant tumors.  Diagnosis is primarily based on histopathology but radiologic and intraoperative findings help distinguish it from differentials.  Complete surgical excision remains the treatment of choice, and coupled with good follow up, may improve the prognosis of patients.   Keywords: sinonasal ameloblastoma, extragnathic, craniopharyngioma

AbstractObjective:We report a rare case of small cell neuroendocrine carcinoma of the nasal cavity and paranasal sinuses with intracranial extension, and discuss the management of this rare tumour.Results:Small cell neuroendocrine carcinoma involving the nasal cavity and paranasal sinuses with intracranial extension may be treated successfully with surgery alone, without development of local recurrence.Conclusion:Small cell neuroendocrine carcinoma is a locally aggressive tumour with a high rate of recurrence. Early and aggressive surgical excision with or without radiotherapy or chemotherapy can improve a patient's outcome and prognosis. Regular follow up is needed to detect any local or distant recurrence.

Objectives: Neurilemmoma in the nasal cavity and paranasal sinuses is very rare. The study aimed to improve the understanding of neurilemmoma in the nasal cavity and paranasal sinuses. Materials and Methods: The clinical data of 10 patients with neurilemmoma in the nasal cavity and paranasal sinuses treated from January 2014 to June 2019 in our hospital were retrospectively studied. Results: There were 6 females and 4 males patients in our study. The mean age was 49.5 years (range 37-77 years), and the most common clinical symptom was unilateral nasal obstruction. The site of tumor included the nasal cavity, maxillary sinus, ethmoid sinus, and sphenoid sinus. There were 2 cases with malignant neurilemmoma. Nine patients underwent functional endoscopic sinus surgery (FESS); however, 1 patient underwent FESS combined with the lateral rhinotomy for complete resection of the tumor. Two patients with malignant neurilemmoma received postoperative radiotherapy. The mean follow-up was 3.82 years (range 2-7 years). There were no incidences of tumor recurrence during the study period. Conclusions: Neurilemmoma in the nasal cavity and paranasal sinuses is a mainly benign tumor. Complete surgical excision by FESS is the only treatment option for neurilemmoma in the nasal cavity and paranasal sinuses; while malignant neurilemmoma needs postoperative radiotherapy.

Abstract Meningiomas arise from arachnoid cells. They can occur at intracranial or extracranial sites. Extracranial meningiomas are very rare tumors. They may arise from nasal cavity, paranasal sinuses, middle ear, and subcutaneous tissues. The ectopic meningiomas of paranasal sinuses do not have any communication with intracranial meninges. They usually occurs in young males. Imaging studies shows no bone erosion or intracranial extension. Primary surgical excision is the treatment of choice. The present case is reported due to its rarity and presentation at an unusual age.

Cholesterol granuloma (CG) is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. This article reports a case of CG in the maxillary sinus of a 22-year-old man, manifesting as a swelling on the right maxilla associated with pain and nasal obstruction. Computed tomography (CT) imaging showed complete opacification of the right maxillary sinus with cortical bone expansion and destruction. Incisional biopsy showed a solid mass filling the sinus and histological examination showed foreign body reaction to cholesterol crystals. The microscopic findings associated to tooth vitality, CT images and absence of a cavity during the surgical procedure were compatible with the diagnosis of CG of the maxillary sinus. Complete surgical excision of the mass under general anesthesia was suggested, but the patient did not return to conclude the treatment. CG must be included in differential diagnosis of diseases that cause opacification on the paranasal sinuses, especially sinusitis, and cystic and tumoral lesions.

This case is related to a 52-year-old lady with proptosis, diplopia and diminution of vision due to a mass lesion in upper medial quadrant of the orbit. CT scan revealed a well defined mass in basi-frontal area with intra-orbital and intracranial extension. On exploring it was found to be mucopyocele of the frontal sinus. Surgical excision was done by external approach. The symptoms and signs resolved completely within a week. Frontal sinus mucopyoceles are benign and curable. Early recognition and management of them is of paramount importance because they can expand and cause local, orbital or intracranial complications.

AbstractChondrosarcomas are the second most common primary malignant bone tumors. Head and neck chondrosarcomas constitute less than 10% of these tumors, rarely arising from the nasal septum. These are locally aggressive malignant tumors arising from the cartilaginous framework of the nasal septum. Rarity of the tumor coupled with nonspecific symptoms makes it a diagnostic dilemma. Diagnosis requires endoscopy, radiology, and final histopathology for confirmation. Treatment is mainly surgical, requiring complete surgical excision with clear margins. Radiation has a role in unresectable tumors or for tumors with positive margins after surgery. Survival depends on the grade of tumor that predicts the metastatic potential of the tumor. We present a rare case of chondrosarcoma arising from the nasal septum in a 29-year-old young female presenting with complaints of nasal obstruction. Computed tomography was suggestive of a calcified cartilaginous tumor arising from the nasal septum. Endoscopic excision was done and postoperative histopathology showed grade II chondrosarcoma with clear margins. No adjuvant treatment was given to our patient and 2 years post-excision patient is disease free.To conclude, chondrosarcoma of the nasal septum is a rare tumor, with nonspecific symptoms. Surgery with clear margins remains the treatment of choice. Prognosis depends on the extent of tumor at presentation, resection margins, and grade of tumor.

Solitary papilloma in the respiratory tract is a rare benign epithelial tumor which is complete surgical excision of the current standard treatment for this type of tumor. Here a case of solitary tracheal papilloma treated by surgical resection is reported. Due to rarity and non-specific symptoms, tracheal papilloma always subjected to misdiagnosed and suffer from delayed treatment. In this case, a forty two years male has been presented with a recurrent non-productive irritative cough, a progressive shortness of breath, expiratory stridor and occasional hemoptysis. The patient was previously diagnosed as a case of bronchial asthma by a Pulmonologist and wrongly treated as well. CT scan revealed an intraluminal tracheal mass arises from the right side of the tracheal wall opposite c6-c7 vertebrae. The tumour was removed by endoscopic excision. The histopathological result confirms the diagnosis of squamous cell papilloma. No complications occur during surgery and no recurrence was observed in six months after surgery on followup.

Abstract Context.—Smooth muscle tumors (SMTs) of the sinonasal tracts are very rare mesenchymal neoplasms, and the literature includes very limited data correlating histologic parameters with clinical outcome. As the behavior of SMTs is site-dependent, defining applicable criteria to distinguish among low-grade leiomyosarcoma, SMT of uncertain malignant potential (SMTUMP), and cellular leiomyoma is sometimes difficult and arbitrary. Objective.—To correlate the clinicopathologic features of 12 well-differentiated sinonasal SMTs with MIB-1 index and clinical outcomes so as to better classify this group of tumors. Design.—Twelve cases of sporadic well-differentiated SMTs arising from the sinonasal tract were retrieved from both institutions. High-grade leiomyosarcomas were excluded from this analysis. The histologic parameters assessed included circumscription, mucosal ulceration, cellularity, nuclear atypia, mitotic count, necrosis, and destruction of adjacent bony structures. The histologic classification of these tumors was based on the guidelines for SMTs of deep soft tissues, using greater than 4 mitotic figures (MF)/10 high-power fields (HPF) to separate SMTUMP from leiomyosarcoma and the presence of 1 to 4 MF/10 HPF to distinguish between leiomyoma and SMTUMP. Immunostaining of MIB-1 index was performed in 7 cases with available material. Results.—This study showed a 1:1.5 male-female ratio and a mean age of 40 years (range, 20–67 years). The most frequent symptoms were nasal stuffiness and/or epistaxis. The tumors involved nasal cavity in 8 cases (67%), paranasal sinus alone in 2 cases (16.5%), and both nasal cavity and paranasal sinuses in 2 cases (16.5%). The tumors ranged in size from 0.3 to 5.5 cm (mean, 2 cm) and were classified as follows: 7 leiomyomas, 2 SMTUMPs, and 3 low-grade leiomyosarcomas. All 7 leiomyomas, 1 SMTUMP, and 1 leiomyosarcoma originated from vessel walls. Bone involvement was seen in both the SMTUMPs (1 of 2) and leiomyosarcomas (2 of 3). Focal infiltrative growth was observed only in the 3 leiomyosarcomas, 1 of which also showed microscopic coagulative tumor necrosis. Mitotic figures ranged from 0 to 10 (mean, 2.3), with absence of mitosis in all 7 leiomyomas, 1 to 4 MF/10 HPF in the 2 SMTUMPs, and more than 4 MF/10 HPF in the 3 low-grade leiomyosarcomas. The MIB-1 index was low (≤5%) in both leiomyoma and SMTUMP groups, while the leiomyosarcomas showed a higher (≥15%) proliferative index. All 12 patients were treated by surgical excision, and only 1 patient with leiomyosarcoma received postoperative radiation. In all 12 tumors, there was neither local recurrence nor distant metastasis after an average of 93 months of follow-up (range, 4–221 months). Conclusion.—Well-differentiated sinonasal SMTs are rare and occur in adults with a slight female predilection. The lesions confined within the nasal cavity were more common than those involving a single paranasal sinus or both nasal cavity and paranasal sinuses. Despite variations in location, clinical manifestation, histologic features, and MIB-1 index, these tumors appear to follow a favorable course. Complete surgical excision appears to provide adequate treatment for these patients.
