RESUMEN
Sinonasal organized hematoma is a rare condition characterized by an organizing blood clot in the sinonasal cavity, which consists of blood products, fibrin, and dilated blood vessels. As a benign entity with an aggressive imaging appearance, it is important to differentiate sinonasal organized hematoma from malignancies affecting the paranasal sinuses and nasal cavities to guide appropriate management. In this report, we discuss the clinical presentation and diagnostic evaluation of an 82-year-old male with a left maxillary sinus organized hematoma and provide a comprehensive review of the relevant literature.
RESUMEN
BACKGROUND: The recommendation for management of intraductal papilloma has not been clearly established and its surgical excision criteria remain controversial. This study determines the institutional malignancy upstage rate of benign intraductal papillomas and identifies risk factors for upstage. METHODS: Retrospective review was conducted on female patients who were diagnosed with intraductal papillomas without atypia on core needle biopsy at Atrium Health Wake Forest Baptist Hospital between 1/2012 and 6/2021. Patients were excluded if there was a concomitant malignancy or atypia or deemed to be discordant with imaging. Features associated with upstage on imaging and histopathology were obtained from the electronic medical record. RESULTS: This study included 245 intraductal papillomas without atypia in 231 women (mean age, 59.1 ± 12.3 [SD] years). Approximately 31% (76/245) of the papillomas were excised, whereas 69% (169/245) of the papillomas underwent surveillance. Of the patients who underwent excisional biopsy, upstage rate for DCIS was 1.3% (1/76) and 5.3% (4/76) for atypia. All of the papillomas upstaged to DCIS or atypia had lesion size ≥10 mm on imaging. Out of the 139 intraductal papillomas that underwent radiologic surveillance, two (1.4%) developed malignancy and three (2.2%) developed atypia. DISCUSSION: The risk of upstaging of intraductal papilloma without atypia to malignancy remains extremely low. Therefore, routine surgical excision may not be necessary. While the papillomas upstaged to either malignancy or atypia have size abnormality ≥10 mm, other potential selective excision criteria should be explored to further decrease the risk of an upstage.

BACKGROUND: The management of flat epithelial atypia (FEA) on core needle biopsy remains controversial. The upstaging rates after surgical excision are variable. In this study, we seek to determine the upstaging rate of FEA at our institution. METHODS: Patients with a diagnosis of FEA were identified from the institution's pathology database from 2009 to 2018. Patients were included in the study if FEA alone, without atypia or cancer, was identified on core needle biopsy. Patient demographics, imaging, management, and pathology characteristics were obtained. Statistical analysis performed using IBM SPSS 26.0 (Armonk, NY, USA). RESULTS: FEA was diagnosed on core needle biopsy in 235 patients from 2009 to December 2018. Forty-eight patients met the inclusion criteria. The majority of patients presented with calcifications on mammogram (n = 21, 64%) with the remainder as masses (n = 6, 18%) or architectural distortion (n = 6, 18%). Of those, 15 (31%) patients declined surgical excision, of which none developed cancer over a mean follow-up of 4.4 years. Of the 33 (69%) patients undergoing excisional biopsy, 17 (52%) confirmed FEA, 11 (33%) had benign findings, and 3 (9%) demonstrated atypical ductal hyperplasia on final pathology. One (3%) case revealed ductal carcinoma in situ (DCIS) and 1 (3%) was upgraded to invasive cancer for an overall upstaging rate of 4% (2/48). After a mean follow-up of 3.4 years, none of the excisional biopsy patients developed invasive breast cancer. Adjuvant therapy was used in the cases of DCIS and invasive cancer; however, chemoprevention with raloxifene or tamoxifen was not chosen by any of the remaining patients. CONCLUSION: In our cohort, expectant management of FEA alone appears to be a safe option as our upstaging rate to DCIS or invasive cancer for FEA diagnosed on core biopsy was only 4%. Our study suggests that close follow-up is a safe and feasible option for pure FEA without a radiographic discordance found on core biopsy.
