Fungal rhinosinusitis: a retrospective analysis of clinicopathologic features and treatment outcomes at Ramathibodi Hospital.

The objective of this study was to determine the clinicopathologic findings of invasive and non-invasive fungal rhinosinusitis and to compare the features of the two diseases. The medical records of patients with invasive and noninvasive fungal rhinosinusitis at Ramathibodi Hospital between July 1999 and June 2009 were analyzed. The criterion for the diagnosis of fungal rhinosinusitis was the evidence of fungal elements from histopathologic section on sinonasal specimens. The age, gender, clinical manifestations, duration of symptoms, associated diseases, laboratory data, results of mycotic culture and treatment outcomes were analyzed. The relationship between fungal rhinosinusitis and patient characteristics as well as clinical presentations were assessed. The fungus-attributable mortality rate was determined. The study included 43 cases of invasive fungal rhinosinusitis and 68 cases of non-invasive fungal rhinosinusitis. There were 44 male, and 67 female patients. The mean age at diagnosis was 54.6 years (range: 5 to 86 years). A total of 70 (63.1%) were attributed to aspergillosis, 8 (7.2%) to candidiasis, 6 (5.4%) to zygomycosis, 4 (3.6%) to phaeohyphomycosis, 1 (0.9%) to pseudallescheriasis, 1 (0.9%) to entomophthoromycosis and 21 (18.9%) to nonspecific fungi. Cultures from sinonasal tissues were positive for fungus in 37 of 87 cases (42.5%). The clinical presentations of fungal rhinosinusitis included nasal stuffiness (27.9%), nasal discharge (27.9%), facial pain (27.9%), fever (24.3%) and headache (19.8%). One-fifth of cases had an underlying hematologic malignancy. Invasive fungal rhinosinusitis was significantly associated with hematologic malignancy and neutropenia. Fungus-attributable mortality rate was 44.2% in invasive fungal rhinosinusitis. Early antifungal therapy and surgical drainage were associated with a survival advantage.

Expression of hormonal receptor in patients with metastasizing pleomorphic adenoma of the major salivary gland; a clinicopathological report of three cases.

BACKGROUND: Metastasizing pleomorphic adenoma is an uncommon malignant tumor of the salivary gland demonstrating benign epithelial and modified myoepithelial elements intermingling with tissue of mucoid, myxoid, or chondroid appearance that inexplicably manifests local or distant metastasis. OBJECTIVE: To determine the expression of hormonal receptor in the patients with metastasizing pleomorphic adenoma of the major salivary gland. MATERIAL AND METHOD: Medical records, clinical and pathologic findings of three patients who were diagnosed as metastasizing pleomorphic adenoma were reviewed. The immunohistochemical stains for estrogen receptor, progesterone receptor, and Ki-67 were performed. RESULTS: Three cases of metastasizing pleomorphic adenoma, clinically presenting as painless, gradually enlarged cervical lymph nodes were reported. The pathologic examinations of the cervical lymph nodes are morphologically and immunohistologically identical to the sialoadenectomy specimen. Immunohistochemical stains show positive reactivity to progesterone receptor but negative reactivity to estrogen receptor in both mesenchymal and epithelial components of pleomorphic adenoma. CONCLUSION: These are the first reported cases of metastasizing pleomorphic adenoma of the major salivary glands associated with expression of progesterone receptor in both specimens of sialoadenectomy and lymph node biopsy. This finding supports the pathogenesis of benign metastasis of tumor. However, the role of hormonal receptor in the pathogenesis and treatment of salivary metastasizing pleomorphic adenoma should be further investigated.

Clinicopathologic Findings and Treatment Outcome of Laryngectomized Patients with Laryngeal Cancer and Hypopharyngeal Cancer: An Experience in Thailand

Objective: To evaluate the clinicopathologic findings and treatment outcome in laryngectomized patients with laryngeal cancer and hypopharyngeal cancer. Materials and Methods: The authors retrospectively reviewed the medical records of 212 patients who had been newly diagnosed and treated with laryngectomy between January 2000 and December 2010. The age, gender, clinical manifestations, associated predisposing condition, tumor WHO grade, AJCC tumor stage, maximum tumor size, anatomical involvement, type of surgery, postoperative sequelae, treatment and therapeutic outcome were analyzed. Results: The present study included laryngeal cancer (n = 155) and hypopharyngeal cancer (n = 57). The patients' age ranged from 38 to 84 years, with the mean age of 62.08±9.67 years. The common clinical presentations were hoarseness (73.6%), cervical lymphadenopathy (35.8%), sorethroat (22.2%), and odynophagia (14.6%). The laryngeal cancer commonly involves true vocal cord (86.5%), anterior commissure (65.8%), false vocal cord (56.8%), laryngeal ventricle (53.5%), subglottis (47.1%), and paraglotic space (35.5%), respectively. Fifty-three percent of cases had stage IV cancer. The most common postoperative surgical sequela was hypothyroidism (77.8%). The overall 5-year survivals for laryngeal cancer and hypopharyngeal cancer were 55% and 9%, respectively. The 5-year survival for node-negative cases was 61.8% versus 17% for node-positive cases (p< 0.001). AJCC stage of laryngeal cancer and hypopharyngeal cancer was a significant predictor of 5-year survival (p< 0.001 and p = 0.004, respectively). Conclusions: The advanced AJCC stage, advanced T stage, advanced N stage, extracapsular tumor spread, and tumor invasion of false vocal cord, epiglottis, preepiglottic space, paraglottic space, thyroid cartilage, cricothyroid membrane were found to significantly augment the decrease of 5-year survival in laryngeal cancer. Only advanced AJCC stage was significantly associated with 5-year survival rate in hypopharyngeal cancer.
