The management of thyroid papillary microcarcinoma (PMC) is controversial. Total thyroidectomy, thyroid lobectomy/isthmectomy, and even no treatment have been proposed. We investigated the clinical course and prognostic factors for disease recurrence and distant metastasis in 445 patients with PMC. Data from 445 patients diagnosed with PMC in the period from 1978 to 2003 were reviewed and analyzed. Total thyroidectomy was performed in 404 patients and loboisthmusectomy in 41. Neck dissection took place in 226 patients (49.7%), with 166 of only the central compartment and 60 of both the central and lateral compartments. Radioiodine ((131)I) ablation treatment was given to 389 patients. Median tumor size was 7 mm (range 1-10 mm). PMC was multifocal in 156 cases (35%) and bilateral in 60 cases (13.5%). Extrathyroidal tumor extension (pT3) and neck lymph node metastasis (pN1) were present in 133 (30%) and 182 (40.9%) patients, respectively. Capsular invasion without extrathyroidal tumor extension was observed in 39 (8.7%) patients. Mean follow-up was 5.3 (range 1-26) years. Seventeen (3.8%) patients had recurrence or persistence of disease: neck recurrence (NR) in 12 (2.7%), distant metastasis (DM) in four (0.9%), NR + DM in one (0.2%). One patient (0.2%) died of the disease. Capsular invasion, extrathyroidal tumor extension (pT3), and neck lymph node metastasis at presentation (pN1) were the only independent risk factors for NR and/or DM occurrence (p < 0.05). Patients not showing these features, who were treated with loboisthmusectomy only, never experienced disease recurrence. Total thyroidectomy seems advisable in PMC with extrathyroidal extension and neck lymph node metastasis at presentation. Capsular invasion without extrathyroidal extension may suggest aggressive tumor behavior and require radical treatment.

Ear, nose and throat (ENT) involvement is common in Churg-Strauss syndrome (CSS), usually manifesting as allergic rhinitis and chronic rhinosinusitis with or without polyps. Otolaryngologists may play a pivotal role in making an early diagnosis of this disease. CSS is a systemic vasculitic disorder that affects small to medium-sized blood vessels. Although the cause of CSS remains unknown, tissue damage seems more likely to be mediated by activated eosinophils. Patients affected by CSS frequently have ENT manifestations, which are often present at the time of disease onset and may represent relevant clues for the diagnosis. Thus, our objective was to present the ENT manifestations at the onset, at the diagnosis and at some point during the course of the disease in a series of patients with CSS collected at a single center. Twenty-eight patients with CSS, as defined according to the 1990 American College of Rheumatology classification criteria, were identified. Twenty-one (75%) of these patients had ENT involvement. We evaluated the clinical course, laboratory data, histologic findings, treatment and outcomes. Of the 21 patients, 13 (61.9%) had ENT involvement at asthma onset and 8 (38%) at diagnosis or during follow-up. The most common ENT manifestations were allergic rhinitis in 9 (42.8%) patients and nasal polyposis in 16 (76.1%). Three (14.2%) patients developed chronic rhinosinusitis without polyps, three (14.2%) had nasal crusting, one (4.7%) serous otitis media, one (4.7%) purulent otitis media, two (9.5%) progressive sensorineural hearing loss, and one (4.7%) unilateral facial palsy. Corticosteroid therapy associated with immunosuppressive drugs usually yielded improvement or stabilization.
