Vocal Polyp

Novel molecular techniques including markers of laryngeal carcinogenesis could improve the difficult diagnosis of a wide array of laryngeal polypoid changes. The case reported herein shows that not every clinically diagnosed vocal fold polyp is a benign lesion as mostly considered in the literature. Further assessment including carcinogenesis markers detected a nest of micro-invasive squamous cell carcinoma. Therefore, we recommend biopsy backed up with immunohistochemical analysis whenever there is a suspicious polypoid formation in order to exclude or confirm a malignant transformation because of the possibility of multi-focal growth in the active laryngeal epithelium.

Cutaneous squamous cell carcinoma is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies. We report the case of a patient who presented with a complaint of nonhealing wounds following radiation therapy for the treatment of noninvasive squamous cell carcinoma of both lower extremities. Initial biopsies of the wounds were benign. However, a second biopsy performed approximately 2 months later was found to be positive for invasive squamous cell carcinoma. This case uniquely exemplifies that all nonhealing wounds should be viewed with a critical eye for possible malignancy even in the presence of previous negative biopsy. This is especially true for radiation wounds that may be prone to malignant transformation or recurrence. (J Am Podiatr Med Assoc 101(4): 360–362, 2011)

<p class="abstract"><strong>Background: </strong>Phonosurgery essentially is surgery defined to improve or restore the voice. The objective of the study was to analyze and categorize the various benign lesions of the vocal cord causing vocal dysfunction requiring phonosurgeries, to analyze the incidence and distribution of cases according to age, sex, and etiology among the patients who require intense medical and voice therapy with surgical intervention.<strong> </strong></p><p class="abstract"><strong>Methods: </strong>This prospective study was conducted in fifty patients with vocal dysfunction from the ear, neck and throat (ENT) outpatient department of Otorhinolaryngology, Mohan Kumaramangalam Government General Hospital, Salem in the year September 2018 to October 2019 who failed conservative medical and voice therapy requiring phonological procedure were included in this study. Phonomicrosurgery was done for the patients with benign vocal fold mucosal disorders and medialization laryngoplasty using Gore-Tex was done for the patients with unilateral vocal cord palsy causing vocal dysfunction.</p><p class="abstract"><strong>Results: </strong>The present study on phono surgery concludes vocal polyp is the commonest benign lesion of the vocal cord that constitutes 40% in our study population. Males are affected more than females. Proper investigation of voice and larynx provides the exact pathological nature of the lesion and determines the timing of surgical intervention.<strong></strong></p><p class="abstract"><strong>Conclusion: </strong>Most of the patients who underwent medialization laryngoplasty using Gore-Tex also had a good outcome at the end of the voice therapy.</p><p> </p>

Abstract Inverted papilloma is an uncommon tumor mostly arising from the lateral wall of the nasal cavity and displays a benign but locally aggressive behavior. Intracranial extension is an extremely rare presentation of inverted papilloma. Extension occurs either as a benign lesion or due to malignant transformation. We report a case of concurrent inverted papilloma and squamous cell carcinoma presenting with epistaxis and recent-onset altered behavior and memory impairment. After literature review of similar cases having inverted papilloma with intracranial extension, we could identify a total of 12 cases, most of which were recurrences of a primary inverted papilloma that were resected before extension into the cranial cavity. Most cases were of extradural extension, and intradural spread resulted in poor prognosis on follow-up. Concurrent inverted papilloma and squamous cell carcinoma extending into the anterior cranial fossa and frontal lobe is a very rare clinical entity and can present as frontal lobe syndrome.

Objective This study aimed to examine the clinicopathological characteristics, treatment, and prognostic factors in 12 cases of malignant transformation of mature cystic teratoma of the ovary (MCTO). Methods We performed a retrospective study of 12 patients with malignant transformation of MCTO who were admitted to the Affiliated Hospital of Qingdao University from 2003 to 2019. We examined case records, clinical parameters, and biological assessments. Results The median age of the patients was 56.5 years and seven of them were postmenopausal. The average tumor size was 18.5 cm. All patients had pelvic masses at their first hospital visit. Nine of the patients had discomfort in the lower abdomen, two presented with a lower abdominal palpable mass, and three were complicated by fever. The median follow-up time was 73 months (12‒193 months). Ten patients survived with a disease-free status and two died. Conclusions There is a low incidence of malignant transformation of MCTO, and its most common histological type is squamous cell carcinoma. Age and tumor size are important factors in malignant transformation of teratomas. While there is a lack of treatment guidelines for malignant transformation of MCTO, early diagnosis and treatment may be beneficial for these patients.

Adrenal cortical carcinoma (ACC) is a rare cancer with poor prognosis that needs to be distinguished from adrenocortical adenomas (ACAs). Although, the recently developed transcriptome analysis seems to be a reliable tool for the differential diagnosis of adrenocortical neoplasms, it is not widely available in clinical practice. We aim to evaluate histological and immunohistochemical markers for the distinction of ACCs from ACAs along with assessing their prognostic role. Clinical data were retrospectively analyzed from 37 patients; 24 archived, formalin-fixed, and paraffin-embedded ACC samples underwent histochemical analysis of reticulin and immunohistochemical analysis of p27, p53, Ki-67 markers and were compared with 13 ACA samples. Weiss and Helsinki scores were also considered. Kaplan−Meier and univariate Cox regression methods were implemented to identify prognostic effects. Altered reticulin pattern, Ki-67% labelling index and overexpression of p53 protein were found to be useful histopathological markers for distinguishing ACAs from ACCs. Among the studied markers, only pathological p53 nuclear protein expression was found to reach statistically significant association with poor survival and development of metastases, although in a small series of patients. In conclusion, altered reticulin pattern and p53/Ki-67 expression are useful markers for distinguishing ACCs from ACAs. Immunohistopathology alone cannot discriminate ACCs with different prognosis and it should be combined with morphological criteria and transcriptome analysis.

Squamous cell carcinomas are often seen on the sun-exposed areas of the skin and are rarely observed on the digits of the foot. However, there have been incidences of squamous cell carcinoma developing in the presence of chronic wounds with osteomyelitis, thus complicating the treatment. We present a patient with osteomyelitis who developed invasive squamous cell carcinoma of the third digit. We conclude that wounds with osteomyelitis may have underlying pathologic abnormalities that are not obvious on initial presentation.
