In Morocco, the purpose of the National Cancer Prevention and Control Plan (PNPCC) is to decrease the incidence, mortality, and morbidity attributable to cervical cancer (CC), including the general objective which is to improve women´s care by setting up an organized system for screening, early diagnosis and treatment of this disease, and as operational objectives an: 1) achievement of at least 30% of the annual coverage rate by cervical cancer (CC) screening; 2) achievement of at least 80% of the rate of participation in CC screening per screening cycle; 3) achievement of 100% of the treatment rate for precancerous lesions screened within the framework of the program. CC screening concerns all women aged 30 to 49 years old. Women who have already had CC and pregnant women from the 8th week of amenorrhea until the 6th week postpartum are excluded from the program. The screening test currently used is the naked eye inspection with acetic acid or visual inspection with acetic acid (VIA), which will be followed by a colposcopy exam and biopsy if a precancerous lesion is confirmed. The VIA is carried out at the level of urban and rural health centers, by a trained health professional. Knowing that the pap-smear test was widely used before. Thermo coagulation, also called: cold coagulation, is currently the main treatment for intraepithelial lesions (LIE) that are eligible for this treatment, and finally the national program has introduced anti-HPV vaccination within the national vaccination program (NPI).

Primary thoracic cancers affect a large number of patients, mainly those with lung cancer and to a lesser extent those with pleural mesothelioma and thymic tumours. Given their frequency and associated comorbidities, in patients whose mean age is high, these diseases are associated with multiple complications. This article, the last of a series dedicated to emergencies in onco-haematological patients, aims to present a clinical picture of the severe complications (side effects, immune-related adverse events) associated with systemic treatments, excluding infections and respiratory emergencies, with which general practitioners and specialists can be confronted. New toxicities are to be expected with the implementation of innovative therapeutic approaches, such as CAR-T cells, along with immunomodulators and antibody-drug conjugates.

First case of radiation-induced parotid leiomyosarcoma.

In 2022, the 5th edition of the WHO classification of Head and Neck tumors was published online. In the salivary gland chapter, a new benign entity, the keratocystoma, was introduced. The sclerosing polycystic adenosis has been recognized as tumoral and is now termed sclerosing polycystic adenoma. The striated duct adenoma now has its own dedicated chapter. Additionally, a new variant of pleomorphic adenoma, termed "canalicular adenoma-like," has been incorporated. Regarding malignant tumors of the salivary glands, significant doubts now exist regarding the actual existence of oncocytic carcinoma, which has been reclassified among emerging entities. Two new malignant entities have also emerged: microsecretory adenocarcinoma and microcystic sclerosing adenocarcinoma. Finally, primary mucinous adenocarcinoma of the salivary glands has been acknowledged as a distinct entity.

Lymphadenopathies are a major cause of consultation in internal medicine, with various causes of diagnosis. Unexplained persistent lymphadenopathy must be biopsied to rule out malignant tumor.

In recent years, several nasal cavity and sinus entities have been described with fusion genes. Salivary gland tumors with fusion genes will not be discussed in this article, but it should be kept in mind that accessory salivary glands are present in the nasal cavity and sinuses and can therefore lead to tumoral lesions. Entities with specific or more frequently described rearrangements in the nasal cavities and sinuses are DEK::AFF2 squamous cell carcinomas,;non-intestinal and non-salivary nasosinusal adenocarcinomas, some of which displaying ETV6 gene rearrangements; biphenotypic nasosinusal sarcomas, most of which displaying PAX3 gene rearrangements; and Ewing's adamantinoma-like sarcomas, which display the same rearrangements as conventional Ewing's sarcomas, mainly the EWSR1::FLI1 rearrangement. Each entity will be described morphologically, immunohistochemically, and prognostically.

Salivary gland tumors represent a diagnostic challenge for pathologists due to their rarity, their very wide histopathological and immuno-phenotypic spectrum, and the recent identification of new entities. This article presents the main molecular characteristics of these tumors in order to allow any pathologist to perceive the diagnostic tracks of these ENT tumors and to better guide the molecular approach to establish the diagnosis and guide therapy.

Synovialosarcoma is a malignant mesenchymal tumor of young adults that occurs in the deep soft tissues, particularly around large joints. When it occurs in more unusual sites, it could present a significant diagnostic challenge. In this case, a 19-year-old girl was treated for a pyloric mass. A pyelic urine cytology performed simultaneously with a pyloric biopsy proved to be a significant element of orientation and perfectly concordant with the histopathological aspect of the pyelic mass after nephrectomy. We report here the first case of renal synovialosarcoma documented in pyelic urine.

The neuroepithelial tumor with PATZ1 fusion is a recently described tumor type, at the border between central nervous system and mesenchymal tumors. The histopathological diagnosis of this neoplasm, not recognized by the 2021 WHO classification, is challenging due to its varied and non-specific morphologic features. Most cases are densely cellular with monomorphous nuclei. Perivascular pseudo-rosettes of the ependymal type and astroblastic features are frequent. Blood vessels may be hyalinized. The tumor may display low- or high-grade features. OLIG2 and GFAP are variably expressed. Guided by DNA methylation profiling, a pathologist aware of this tumor type will search for a fusion involving PATZ1 and EWSR1 or MN1. The physiopathology of neuroepithelial tumor with PATZ1 fusion is not fully understood. The prognosis appears to align with that of intermediate-grade tumors but follow-up data are scarce. The therapeutic management is often similar to that of high-grade neoplasms. Nonetheless, PATZ1 fusion is a potential therapeutic avenue that may lead to personalized and less aggressive treatments.

The renal vein is an exceptional location for leiomyosarcoma, an aggressive malignant tumor of smooth-muscle origin with a poor prognosis. We report the case of a 55-year-old female patient who consulted for left flank pain that had been present for 6 months. A CT scan revealed a 9.4cm left retroperitoneal mass in contact with the psoas muscle, left kidney, stomach, spleen, left colon and extending up to the pancreas, raising the suspicion of a tumour originating in the retroperitoneal tissues. A biopsy revealed a smooth-muscle cell tumour with a degree of malignancy difficult to define. The patient underwent a monobloc left compartmentectomy, which led to the diagnosis of leiomyosarcoma of the left renal vein. A review of the literature on these rare tumours in this location is presented.
