Squamous Cell Papilloma

This case report of a 20-year-old white woman is the youngest patient with a documented squamous cell carcinoma in a solitary nonirradiated laryngeal papilloma. It is rare for malignant degeneration of solitary squamous cell papilloma to occur in a patient under the age of 40. This case is also unique in that most solitary laryngeal papilloma with or without neoplasm occur in males. Most reported malignant neoplasms in squamous papilloma have been previously treated with irradiation. Because approximately 2% to 3% of solitary laryngeal papilloma have malignant neoplasms, adequate biopsy of the lesion and thorough histologic examination must always be done.

Abstract Background Genital malignant neoplasms in mares are relatively rare. The treatment involve surgical removal of the tumour masses, chemotherapy or both. Case presentation Two elderly warmblood mares, aged 16 and 20 were presented in University Clinic with the lumpy lesions at the region of perineum and left labia. Surgical removals of tumour masses were performed on standing animals. Removed tissues were subjected to histopathological examination which confirmed SCC. Conclusions Clinical and ultrasound examination of reproductive organs in both mares showed no inflammatory or neoplastic changes. Both mares healed within 2 weeks after surgery and showed no signs of tumour recurrence for the following year despite no chemotherapy treatment.

Introduction: Skin tumor incidence has increased over the last several decades. A wide range of tumors are encountered in clinical practice. Accurate identification of skin lesions is vital in ensuring malignancies are not missed and that they are treated early to avoid morbidity and mortality.Materials and Methods: A retrospective cross sectional hospital based study on a series of cases was performed in the Department of Pathology, Patan Academy of Health Sciences, Patan Hospital, Lalitpur, Nepal from April 2011 to March 2016. Data from the histopathology database were analyzed using SPSS version 16.0.Results: During the study period, 410 skin biopsies were received, of which 214 (52.2%) were skin neoplasms. Among them, 175 (81.8%) were benign and 39 (18.2%) were malignant neoplasms. Incidence of keratinocytic tumors was highest followed by soft tissue tumors and melanocytic tumors. Intradermal nevus was the most common benign neoplasm. Among the malignant neoplasms, squamous cell carcinoma was most prevalent (46.1%) followed by basal cell carcinoma (15.3%). Skin neoplasms were present in all age groups with maximum number of benign neoplasms prevalent in 21-30 years and malignant in 51-60 years age group. Mean age was 38 years and 58 years for benign and malignant neoplasms respectively.Conclusions: Histopathological evaluation of skin biopsy is an important tool in diagnosis of skin neoplasms. Intradermal nevus and squamous cell carcinoma was the most common benign and malignant neoplasm respectively. Malignant neoplasms were more common in older patients.

Nevus Sebaceous

Nevus sebaceous is a congenital epidermal hamartoma characterized by hyperplastic changes to the epidermis and adnexa. Nevus sebaceous is associated with an elevated risk of cutaneous neoplasms, most often benign; however, malignant neoplasms, most notably basal cell carcinoma, can also present in these patients. Although a rare occurrence, more often affecting adult patients, squamous cell carcinomas have also been reported to arise at the site of pre-existing nevus sebaceous. Herein we report a unique case of a patient with basal cell carcinoma and squamous cell carcinoma arising concurrently in the same nevus sebaceous.

Histopathological Diagnosis

A murine monoclonal antibody (MAb) 2G3 of the lgG1 type was raised using the human esophageal squamous cell carcinoma (SCC) cell line TE-2. Immunoblotting with 2G3 indicated that the antigen recognized by 2G3 has a molecular weight of 34 kD. Its activity was evaluated by immunoperoxidase and immunofluorescence on frozen and paraffin sections of various normal tissues, normal and benign tumors as well as various established cell lines. The pattern of reactivity revealed that the antigen recognized by 2G3 was expressed mainly by esophageal SCC. The only exception was represented by malignant breast tumors, where it reacted weakly. Scatchard analysis using 125I-labelled 2G3 showed that TE-2 has approximately 7.5 times more binding sites than the MCF-7 breast cancer cell line. The use of this new MAb is therefore proposed for the histopathological diagnosis of esophageal SCC.

Malignant neoplasms of the external auditory canal, middle and inner ear are rare. Squamous cell carcinoma (SCC) is the most common neoplasm to occur in this region. As such primary neoplasms of the external auditory canal and temporal bone are uncommon, as these structures more frequently are involved by the cutaneous squamous cell carcinoma (cSCC) of pinna or metastatic cSCC involving parotid gland or post auricular lymph nodes.

Abstract Background: Squamous cell carcinoma is the most common epithelial tumor of the esophagus. Upper endoscopy with multiple minimally invasive biopsies should be performed to confirm the diagnosis. Leiomyoma of esophagus is rare, but it’s the most common benign submucosal mesenchymal tumor of the esophagus. The simultaneous occurrence of an overlying epithelial lesion and a mesenchymal lesion is very rare. This study aims to show a case operated due to squamous cell carcinoma of esophagus that was postoperatively diagnosed with coexistent esophageal leiomyoma and provide a clear overview of the existing literature on it. Case presentation: The patient was a 41-year-old lady who underwent three field esophagectomy (McKeown). In reviewing the pathology slides, the patient had poorly differentiated squamous cell carcinoma and also multiple leiomyomas. A leiomyoma was coexisted with an invading overlying squamous cell carcinoma. Conclusion: It is concluded that esophageal carcinomas may coexist with leiomyomas; preexisting benign tumors may have played an important role in the development of carcinoma by inducing constant stimulation of the overlying mucosa; endoscopic ultrasonography is recommended to avoid overestimating the extent of tumor invasion and the resultant aggressive radical surgery; and esophageal resection is still the modality of choice in treatment in developing countries and also countries with limited equipment.

Background: Carcinoma of unknown primary origin (CUP) comprises various malignancies classified by detection of tissue-specific genes through immunohistochemistry (IHC). We aimed to explore the role of available immunohistochemical markers in diagnosing and classifying malignant neoplasms of unknown primary origin.Methods: A cross-sectional study included 141 patients diagnosed histologically as CUP and referred to the Histopathology and Immunohistochemistry Department, Khartoum Oncology Hospital, from 2012 to 2017. Hematoxylin and Eosin (H&E) and immune stained slides used in the workup were reviewed and classified into the main histologic types of CUP. Data were -analyzed by SPSS. Results: Out of 4436 cases, CUP represents (3.2%). The age group (60-69) years have the highest percentage (20.13%), with male predominance (51.77%). Lymph nodes represent (41.84%) followed by the liver (12.77%), spine (3.55%), and lungs (2.13%). Adenocarcinoma (75.89%) was the most common subtype, followed by undifferentiated neoplasm (14.18%), squamous cell carcinoma (7.09%), and carcinoma with neuroendocrine differentiation (2.84%). In 70 cases (49.6%) of the study cases, the primary site was determined, (17.7%) were given an only differential diagnosis, and in (32.6%) the origin remains unknown. Conclusions: CUP cases during the study period are infrequent (3.2%), and the primary origin was determined in nearly half of patients by the available immune markers. CUP’s common histological types were adenocarcinoma, undifferentiated neoplasm, squamous cell carcinoma, and carcinoma with neuroendocrine differentiation. The most common presenting sites were lymph node, liver, spine, and lungs.

In a 2-year survey of tumors occurring in ruminants reared in El-Dakahlyia Governorate, Egypt during the period from October 2016 to October 2018. 66 tumor masses were collected: 60 from cattle, 2 from buffaloes and 4 from sheep. According to histopathology of cattle tumors, 15 neoplasms were diagnosed as cutaneous papilloma, 5 neoplasms were diagnosed as cutaneous fibropapillomas, 25 neoplasms were diagnosed as squamous-cell carcinoma (SCC) of the eye; 8 neoplasms were diagnosed as SCC of perineum, 1 neoplasm was diagnosed as SCC in skin of muzzle, 2 neoplasms were diagnosed as epulis in dental pad, 2 neoplasms were diagnosed as vaginal leiomyoma, 1 neoplasm was diagnosed as fibroma and 1 neoplasm was diagnosed as liposarcoma. Histopathology of buffalo tumors revealed SCC in head skin (1 case) and buccal cavity (1 case). Histopathology of sheep tumors revealed SCC in skin under the tail (2 cases), skin of groin (1 case) and skin of abdomen (1 case). In conclusion, cattle (60/66) were more susceptible to tumors than buffaloes (2/66) and sheep (4/66). Females accounted for a higher percentage of the neoplasms (47/66) than males (19/66). Adult animals aged above 2 years were more frequently affected than young. The occurrence of epithelial tumors (60/66) was greater than the mesenchymal tumors (6/66). The most common epithelial tumors were ocular SCC and cutaneous papilloma. Number of malignant tumors (41/66) was higher than number of benign tumors (25/66). Variable degrees of bovine SCC differentiation were detected. Meanwhile ovine SCC appeared only well differentiated.
