Our purpose was to collect data on the incidence of malignant skin tumours presenting as chronic leg or foot ulcers in a tertiary centre, and to analyse the frequency and type of initial clinical misdiagnoses in these cases. A retrospective chart review of cases with melanoma or other malignant neoplasms of the skin of the lower extremity treated in a tertiary centre during January 2010 until February 2020 was conducted to identify cases that presented as chronic ulcers. Out of 673 cases, 26 (3.9%) were identified with a total of 27 malignant tumours presenting as chronic ulcers of the lower leg or foot. Therefrom, seven were diagnosed as melanoma, eight as squamous cell carcinoma, and twelve as basal cell carcinoma. The mean interval until diagnosis for all tumour types was 44.4 months (median 24 months). A delay in correct treatment occurred in 12 out of 26 cases (46%) as a result of misdiagnosis with subsequent treatment as chronic leg or foot ulcers of a different etiology. Misdiagnoses were venous ulcer, traumatic wound, mixed arterial and venous ulcer, arterial ulcer, and ulcer of an unknown origin. Malignant ulcers presenting as chronic ulcers are rare, but often lead to misdiagnosis.

Metastatic tumours of pleura are the most common malignant tumours causing malignant pleural effusion. Lungs are the most common primary sites. Primary pleural tumours are rarely seen and diffuse malignant mesothelioma is the most common malignant tumour of pleura. Primary malignant neuroendocrine tumour of pleura is not reported in the literature. Here, we report a rare case of primary malignant neuroendocrine tumour of pleura in a fifty-two-year-old, nonsmoker female who presented with right-sided pleural effusion and ipsilateral, dull aching chest pain. Clinical presentations of inflammatory lesions like tuberculous pleuritis and benign and malignant neoplasms of pleura are indistinguishable; hence, fluid cytology, pleural biopsy, and immunohistochemistry are necessary for exact tissue diagnosis of the tumours, which is mandatory for correct treatment and prognostic assessment.

Abstract Background Upper urinary tract urothelial carcinoma (UTUC) with multiple pathological types is extremely rare in the clinic, but the recurrence rate and mortality these patients are high. At present, there is no standard treatment for such cases. Case presentation We reported a case of ureteral urothelial carcinoma with squamous cell carcinoma and sarcomatoid carcinoma differentiation and rapid ileal metastasis and reviewed the literature related to different pathological types of upper urinary tract tumours to explore the diagnosis, treatment and prognosis characteristics of the disease, enhance our understanding of its clinical manifestations and history of evolution and provide guidance for avoiding missed diagnosis and misdiagnosis. Conclusion There is no standard treatment for urinary malignant tumours with multiple pathological types; radical surgery is considered a suitable choice. Chemotherapy, targeted drug therapy and immunotherapy may be beneficial to the survival of patients. In short, these patients have a high risk of recurrence and metastasis and a poor prognosis.

Microangiopathic hemolytic anemia (MAHA) can be observed as a paraneoplastic syndrome (PS) in certain tumors. MAHA-related signet ring cell carcinoma (SRCC) of an unknown origin is very infrequent. Herein we present a SRCC case presented with refractory acquired thrombotic thrombocytopenic purpura (TTP). A 35-year-old man applied to the emergency service with fatigue and headache. His laboratory tests resulted as white blood cell 9,020/µL, hemoglobin 3.5 g/dL, platelet 18,000/µL. Schistocytes, micro-spherocytes, and thrombocytopenia were observed in his blood smear. MAHA was present and he was considered as having TTP. Plasma exchange treatment was initiated; however, he was refractory to this treatment. Thorax and abdomen computerized tomography revealed thickening of minor curvature in stomach corpus with hepatogastric and paraceliac lymphadenopathy. Bone marrow (BM) investigation by our clinic resulted as the metastasis of adenocarcinoma. Ulceration and necrosis were observed by gastric endoscopy procedure. Biopsy was taken during endoscopic intervention, which resulted as SRCC. MAHA may be seen as a PS in some tumors, especially gastric cancers. Tumor-related MAHA is generally accompanied by BM metastases. As a result, BM investigation may be used as the main diagnostic method to find the underlying cancer. The clinical course of cases with tumor-related MAHA is usually poor, and these cases are usually refractory to plasma exchange treatment. In conclusion, physicians should suspect a malignancy and BM involvement when faced with a case of refractory TTP.

Background: von Hippel–Lindau (VHL) disease is an autosomaldominant condition characterized by the development of benignand malignant tumours, including cases of renal cell carcinoma(RCC). Early detection of RCC through routine surveillance canlead to decreased morbidity and mortality. Data on the numberof patients in Nova Scotia (NS) who have VHL disease, diseasemanifestations and the frequency and mode of the surveillancehave not previously been collected or reported. This project wasdesigned to obtain that information.Methods: The number and management of patients with VHL diseasewas determined by multiple sources: the Maritime MedicalGenetics Service, patient charts, and pathology, radiology and laboratorydata. The actual surveillance being performed was comparedwith that recommended in the literature.Results: Twenty-one patients from 11 families in NS were identified.Manifestations included cases of RCC (31.6%), central nervoussystem (CNS) hemangioblastoma (73.7%), retinal hemangioma(47.4%), renal cyst (47.4%) and pheochromocytoma (10.5%).Of the 6 patients with RCC, 4 had bilateral tumours, 2 requiredkidney transplants and 1 developed metastatic disease. Routinesurveillance was being done for the CNS in 62.5% of patients,retina in 47.4%, abdomen in 43.8% and urine catecholaminesin only 10.5%. Only 1 of the 6 patients who developed RCCwas undergoing routine abdominal imaging. Surveillance investigationswere ordered by a number of different specialists.Conclusion: Patients with VHL disease in NS have a number of manifestationsassociated with their disease, including RCC, in a similarfrequency to that reported in the literature. The surveillanceof these patients is suboptimal in frequency and coordination.von Hippel–Lindau disease is a complex condition that requiresa coordinated approach to care to ensure proper surveillance andtreatment. Our study highlights current deficiencies and offersan enormous opportunity for improvement.Généralités : La maladie de von Hippel-Lindau (VHL) est une maladieà transmission autosomique dominante caractérisée par la formationde tumeurs bénignes et malignes, dont l’hypernéphrome.Le dépistage précoce de l’hypernéphrome par des examens régulierspeut amener une réduction de la morbidité et de la mortalité. Onne sait pas combien de personnes sont atteintes de VHL enNouvelle-Écosse, quelles sont les manifestations de la maladie chezces patients et quels tests de dépistage sont effectués et à quellefréquence. Le projet décrit ici visait à obtenir ces renseignements.Méthodologie : Le nombre et la méthode de prise en charge despatients atteints de VHL ont été établis à l’aide de plusieurs sources :la Clinique de génétique médicale des Maritimes, des dossiers depatients, des rapports de pathologie et de radiologie et des analysesde laboratoire. Les méthodes de surveillance mises en placeont été comparées aux méthodes recommandées dans la littératuremédicale.Résultats : Vingt et un patients de 11 familles de Nouvelle-Écosseont été cernés. Les manifestations incluaient : hypernéphrome(31,6 %), hémangioblastomes siégeant au niveau du SNC (73,7 %),hémangiomes rétiniens (47,4 %), kystes rénaux (47,4 %) etphéochromocytomes (10,5 %). Sur les six patients porteurs d’unhypernéphrome, 4 avaient des tumeurs bilatérales, 2 ont eu besoind’une transplantation rénale et un patient a présenté des métastases.De tous les patients atteints de VHL, 62,5 % ont subi destests réguliers de dépistage au niveau du SNC, 47,4 %, au niveaude la rétine, 43,8 %, au niveau de l’abdomen, et seulement 10,5 %des patients ont subi des tests réguliers de dépistage des catécholaminesurinaires. Sur les 6 cas d’hypernéphrome, un seulementsubissait des épreuves régulières d’imagerie au niveau del’abdomen. Les tests de dépistage avaient été prescrits par différentsspécialistes.Conclusion : Les cas de VHL en Nouvelle-Écosse présentent un certainnombre de manifestations liées à cette maladie, dont l’hypernéphrome,à une fréquence proche de celle mentionnée dansla littérature. La fréquence et la coordination des épreuves dedépistage sont sous-optimales. La maladie de VHL est une affectioncomplexe nécessitant une bonne coordination des soinsafin d’assurer une surveillance et un traitement adéquats. Cetteétude montre les lacunes actuelles et pointe vers des améliorationssubstantielles.

Squamous cell carcinoma of the vulva is predominantly a disease of postmenopausal women; it accounts for 5% of all female genital malignant neoplasms. Postoperative recovery in two among the five operated patient was late as their vulval wound underwent dehiscence. Other three patients had an uneventful post operative period. Histopathology report showed Squamous cell carcinoma in all the cases. Lymphnodes was negative for malignant cells in all the cases.

Background: Eyelid BCC accounts for more than 90% of Eyelid malignant neoplasms. Various aberrant signalling pathways and genes in Non-Ocular BCC have been found whereas Eyelid bcc remains elusive. Objective: This study aims to find the common DEGs of Eyelid and Non-Ocular BCC using bioinformatic analysis and text mining to gain more insights into the molecular aspects common to both BCC non-ocular and Eyelid BCC and to identify common potential prognostic markers. Material and method: The Gene Expression profiles of Eyelid BCC (GSE103439) and Non-Ocular BCC (GSE53462) were obtained from the NCBI GEO database followed by identification of common DEGs. Protein-Protein interaction and Pathway Enrichment analysis of these screened genes was done using bioinformatic tools like STRING, Cytoscape and BiNGO, DAVID, KEGG respectively. Results: A total of 181 genes were found common in both datasets. A PPI network was formed for the screened genes and 20 HUB genes were sorted which included CTNNB1, MAPK14, BTRC, EGFR, ADAM17. Pathway enrichment of HUB genes showed that they were dysregulated in carcinogenic and apoptotic pathways that seem to play a role in the progression of both the BCC. Conclusion: The result and findings of bioinformatic analysis highlighted the molecular pathways and genes enriched in both Eyelid BCC as well as Non- Ocular BCC. The identified pathways should be studied further to recognise common molecular events that would lead to the progression of BCC. This may provide a window to explore the prognostic and therapeutic strategies common to both BCC. Keywords: Basal cell carcinoma (BCC), Cancer, Microarray, Ophthalmology, Tumour marker

In our day to day ENT practice we commonly come across diseases involving the larynx, the oral cavity and the paranasal sinuses. These range from inflammatory disorders to benign and malignant neoplasms. Carcinomas involving the head and neck region are most commonly squamous cell carcinoma. However, a small proportion of cases present with other variants of carcinoma or infective pathology uncommon for the site. In this study we present three rare cases encountered in the out-patient department, namely, Primary Malignant Melanoma of the larynx, Neuroendocrine Tumor of the nose and paranasal sinuses and Rhinosporidiosis of cheek.

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.

Primary malignant neoplasms account for 10% of all primary cardiac tumours and are represented by sarcomas (mainly angiosarcoma, undifferentiated pleomorphic sarcoma, leiomyosarcoma) and primary lymphomas. They usually infiltrate the cardiac walls, but may be also solely intracavitary, mimicking myxoma.
