Attachment Pattern

Sinonasal inverted papilloma (SIP) is a benign tumor originating from the nasal cavity and paranasal sinuses. Sinonasal inverted papilloma is characterized by local infiltration, high recurrence, and malignant transformation, and its associated dysplasia ranges from mild, moderate, severe, carcinoma in situ (CIS) to invasive squamous cell carcinoma. Sinonasal inverted papilloma with carcinoma in situ (IPwCIS) is the highest degree of dysplasia, which is a stage of malignant transformation of IP. Surgical excision and proper adjuvant therapy can help reduce recurrence rates and suppress further deterioration. In this study, we present a patient with IPwCIS who developed 3 recurrences with a multifocal attachment pattern in less than 18 months. We report the clinical manifestations, development, and treatment process in detail. We also performed a literature review to analyze the characteristics of the disease. Despite comprehensive treatment methods, tumor recurrence and further deterioration of IPwCIS persist.

Objective Sinonasal inverted papilloma (IP) is a typically benign sinonasal tumor with a tendency to recur and the potential for malignant transformation. Varying degrees of dysplasia may be present, of which carcinoma in situ (CIS) is most advanced. We hereby describe the biological and clinical behavior of IP with CIS (IPwCIS). Study Design Retrospective cohort. Setting Tertiary academic referral center. Subjects and Methods Patients who underwent surgical resection for IP between 2002 and 2017. Pertinent clinical data were obtained, and all IPwCIS cases were histologically confirmed. Results In total, 37 of 215 cases (17.2%) were identified with IPwCIS. Mean age was 57 years and 86.5% of patients were male. Median follow-up was 82 months, and the recurrence rate was 27%. The maxillary sinus was the most common primary site (37.8%) and 14 tumors (37.8%) demonstrated multifocal attachment, which was associated with recurrence (odds ratio [OR], 9.7; 95% confidence interval [CI], 1.4-112.8; P = .028). IPwCIS was also associated with multiple recurrences (OR, 2.71; 95% CI, 1.246-5.814; P = .021). Most patients were treated with surgery alone (89.1%) and 4 patients received adjuvant radiotherapy (8.1%). Only 1 patient (2.7%) demonstrated malignant transformation after definitive surgery. Conclusions IPwCIS represents the most severe degree of dysplasia prior to malignant transformation and is associated with higher recurrence rate and multifocal involvement but low rate of conversion to invasive carcinoma. The need for adjuvant therapy remains controversial, and further research into the etiology of the disease is warranted.

Significance Statement: Primary middle ear inverted papilloma is an exceedingly rare finding posing a diagnostic challenge, as symptomatology often mimics common clinical entities like serous otitis media. Clinical and radiological findings are not specific, whilst high recurrence rates, local destruction, and potential malignant transformation constitute an overall demanding surgical challenge, requiring aggressive procedures. We report the case of a primary inverted papilloma of the middle ear, discussing diagnostic and therapeutic issues.

Objective: The aim of this study was to assess the quality of TURBT (transurethral resection of bladder tumor) using surrogate parameters and evaluate adherence to the guidelines regarding the management of bladder tumors. Materials and methods: A clinical audit of all new diagnosis of bladder cancer was undertaken from January 2016 to January 2017. A total of 101 new bladder cancer cases were included. Surrogates of TURBT quality including presence of detrusor in the specimen, rate of re-TUR, presence of carcinoma in situ, and 3-month recurrence rates were analyzed. Adherence to guidelines regarding management of non-muscle invasive bladder cancer including time to re-TUR and utilization of single instillation chemotherapy was evaluated. Results: Absence of detrusor muscle in the specimen of the initial TURBT was noted in 22.8% of the cases. The chance of including muscle in the specimen was almost four-fold for tumors larger than 3 cm. A single instillation of intravesical chemotherapy following TURBT was administered in only 40% of eligible patients; 54.3% of patients had a re-TUR, the majority (61.3%) for high-grade non-muscle invasive bladder cancer on initial TURBT. Re-TUR was done on average 10 weeks after initial TURBT. The 3-month recurrence rate was 36.0% with larger tumors (>3 cm) being more prone to early recurrences. Early recurrences were not affected by intravesical instillations with bacillus Calmette–Guérin or mitomycin C although there was a positive association between the presence of carcinoma in situ on initial resection and early recurrences. Discussion and conclusion: One in two patients will have a re-TUR, and approximately one in two patients will have tumor on re-TUR. Single immediate chemotherapy instillations after TURBT are underutilized. The presence of carcinoma in situ on initial TURBT and tumor size were predictors of early recurrences.

Inverted papilloma is a rare and benign tumour. It affects the nasal cavity and paranasal sinuses, has a high rate of recurrence and is associated with malignant transformation. Only few cases of a poorly differentiated carcinoma arising from inverted papilloma have been reported, none of which in the nasopharynx. We report a case of a 37-year-old female, who presented originally in 2012 with inverted papilloma of the nasal septum which was surgically resected. Nasopharyngeal biopsy from 2014 was reported as carcinoma in situ and treated with local endoscopic resection. Three years later she presented with a solitary lesion of the right Eustachian tube opening, confirmed as invasive poorly differentiated carcinoma. Imaging revealed T4 N2b M0 malignancy with skull base and prevertebral space invasion, likely extension into right temporal lobe and malignant adenopathy. Although rare, malignant transformation of inverted papilloma in unusual places should be considered during workup and monitoring of patients.

The medical records of 34 dogs (median age, eight years) with colorectal mucosal lesions were reviewed. Hematochezia was the most common (82%) presenting sign. Most dogs (79%) presented with solitary masses located in the rectum. After histological review, 12 masses were classified as adenomatous polyps and 22 as carcinoma in situ. Recurrence of clinical signs were common (41%), and malignant transformation of the tumor was documented in 18% of the cases. A higher recurrence rate and malignant transformation occurred in dogs presented with multiple masses or diffuse disease and in dogs initially diagnosed with carcinoma in situ.
