Mesenchymal Tumours

Mesenchymal chondrosarcoma (MC) is a rare cartilaginous tumour that occurs in the extraskeletal locations in about one-third of cases. It is aggressive in behaviour and may involve the lower extremities, central nervous system or spine. Mesenchymal tumours are known for distant metastasis; however, metastasis to bilateral kidneys after treatment has not been reported earlier. We present a case of a soft-tissue intramuscular MC of the thigh in a 38-year-old patient which had been surgically excised after neoadjuvant chemotherapy. The patient presented with bilateral dense calcified renal masses after 6 years, which were cytologically proven as MC metastases. In the evaluation of bilateral calcified renal masses in patients with a history of MC, metastasis should be considered.

Abstract Introduction: Langerhans Cell Histiocytosis (LCH) is a condition of malignant clonal proliferation of myeloid bone marrow cells that more commonly affects children than adults. Furthermore, its presentation remains variable ranging from single organ to multisystem involvement including bone, skin, lymph, liver, spleen, lung, and central nervous system. We report an unusual case of multisystem LCH in an adult female presenting with multiple soft tissue abscesses. Case: We report a case of a 38-year-old female with a past medical history of polysubstance abuse, type 2 diabetes, polycystic ovarian syndrome, and isolated central diabetes insipidus who had multiple hospitalizations for recurrent soft tissue abscesses treated with incision and drainage and antibiotics. Imaging studies revealed multiple osteolytic lesions involving the bilateral iliac crests, acetabulum and femur, as well as an iliopsoas abscess. Given her prior history of isolated central diabetes insipidus, the possibility of LCH as the cause was entertained. Histological evaluation performed on an inguinal soft tissue sample stained positive for CD1a and S100, and a formal diagnosis of Langerhans Cell Histiocytosis (LCH) was made. The patient was treated with chemotherapy with good results. Conclusion: This report presents a rare and unusual case of adult onset multisystem LCH involving bone, skin, lymph, and central nervous system presenting with recurrent large abdominopelvic abscesses. These abscesses may represent a rare and unrecognized form of soft tissue involvement of LCH.

Abstract Background To report a case of acute exudative polymorphous paraneoplastic vitelliform maculopathy in a patient with a history of choroidal melanoma, with metastases to the pancreas, liver, and central nervous system. Case presentation A 63-year-old patient, with a history of enucleation of the right eye due to choroidal melanoma, complained of progressive visual loss during a follow-up visit. Fundoscopic examination revealed multiple small areas of serous retinal detachment scattered throughout the posterior pole and ancillary tests confirmed the diagnosis of acute exudative polymorphous paraneoplastic vitelliform maculopathy (AEPPVM). Screening for systemic metastases showed pancreatic, hepatic, and central nervous system involvement. Conclusions We describe a rare case of acute exudative polymorphous paraneoplastic vitelliform maculopathy, which should be considered in patients with or without a history of melanoma, who have vitelliform retinal detachments. Nevertheless, no previous reviews of literature have shown a correlation between AEPPVM and pancreatic metastasis.

1. The family histories of 722 infants who were born with spina bifida cystica were studied. 2. The index cases were referred for surgical treatment and were not selected in any way from the genetic point of view. 3. Intensive inquiries were made to obtain a complete family pedigree, including a prospective follow-up of siblings born after the index case. 4. Of 1,256 siblings 85 or 6.8% had gross malformation of the central nervous system: spina bifida cystica in 54, anencephaly in 22, and uncomplicated hydrocephalus in 9. 5. Of 306 children born after the index case 25 (8%) or 1 in 12 were affected. 6. There was a progressive increase in multiple cases in the family with increasing family size. In sibships of five or more, multiple cases occurred in 24.1%. 7. In 118 families cases of gross malformation of the central nervous system were known to have occurred among members of the family other than siblings. Cases occurred in three generations. 8. It is possible that spina bifida cystica might be a recessively inherited condition.

Extraskeletal Mesenchymal Chondrosarcoma

Extraskeletal mesenchymal chondrosarcoma is a rare soft tissue sarcoma arising from soft tissues, mainly of the lower extremities, meninges, and orbits. It usually presents during the second to third decades of life, and has a slight predominance in females. Histologically, it has a typical biphasic pattern comprising small cells and islands of hyaline cartilage. It can pose a diagnostic challenge in small biopsy specimens where 1 of the 2 components can be absent. The prognosis is extremely variable; survival varies depending on the location of the tumor.

The main object of the present paper is to furnish a brief account to the knowledgement of Protozoa parasitic in common Brazilian frog of the genus Leptodactylus for general students in Zoology and for investigators that use this frog as a laboratory animal. Hepatozoon leptodactyli (Haemogregarina leptodactyli) was found in two species of frogs - Leptodactylus ocellatus and L. pentadactylus - in which develop schizogony whereas sporogony occurs in the leech Haementeria lutzi as was obtainded in experimental conditions. Intracellular forms have been found in peripheral circulation, chiefly in erythrocytes, but we have found them in leukocytes too. Tissue stages were found in frog, liver, lungs, spleen, gut, brain and heart. The occurence of hemogregarine in the Central Nervous System was recorded by Costa & al,(13) and Ball (2). Some cytochemical methods were employed in attempt to differentiate gametocytes from trophozoites in the peripheral blood and to characterize the cystic membrane as well. The speorogonic cycle was developed in only one specie of leech. A brief description of the parasite is given.

<b><i>Background:</i></b> Venous thromboembolism (VTE) is a frequent, potentially lethal complication in individuals with cancer. Patients with brain tumors are at particularly high risk for VTE. Primary central nervous system lymphoma (PCNSL) is a rare subtype of diffuse large B cell lymphoma, involving the craniospinal axis. The incidence of VTE in patients with PCNSL was reported as very high, occurring mostly in the early period of therapy. <b><i>Objectives:</i></b> We aimed to evaluate the efficacy and safety of prophylactic low-molecular-weight heparin (LMWH) throughout the treatment of PCNSL. <b><i>Patients:</i></b> All patients &#x3e;18 years of age diagnosed and treated for PCNSL at our institution in 2005–2017 were included. <b><i>Results:</i></b> There were 44 patients; mean age at diagnosis was 61.5 years. Three patients (6.8%) had a personal history of thrombosis, 11 (25%) had a history of diabetes or smoking, and 32 (72%) had an Eastern Cooperative Oncology Group performance status of 0–1 at diagnosis. During treatment with LMWH, no VTE events were recorded; 2 (4.5%) patients experienced a minor bleeding event and 1 (2.3%) a major bleeding event. <b><i>Conclusions:</i></b> Among our 44 patients with PCNSL treated with prophylactic LMWH, no VTE events were recorded, and only 1 (asymptomatic) intracranial bleed was recorded. Within the limitations of a retrospective nonrandomized study, our findings suggest that VTE prophylaxis may be beneficial for individuals with PCNSL.

INTRODUCTION Ecstasy, also known as MDMA (3,4, methylenedioxymethamphetamine), is a popular illicit party drug amongst young adults. The drug induces a state of euphoria secondary to its stimulant activity in the central nervous system. PATIENTS AND METHODS A database review at two major inner city hospitals was undertaken to identify patients presenting with pneumomediastinum and their charts reviewed. A Medline review of all reported cases of pneumomediastinum associated with ecstasy abuse was undertaken. RESULTS A total of 56 patients presenting with pneumomediastinum were identified over a 5-year period. Review of the charts revealed a history of ecstasy use in the hours prior to presentation in six of these patients, representing the largest series reported to date. CONCLUSIONS Review of previously reported cases reveals the likely mechanism is due to Valsalva manoeuvre during periods of extreme physical exertion, and not a direct pharmacological effect of the drug.

Objective: Parry-Romberg syndrome (PRS) and en coup de sabre (ECDS) are subtypes of craniofacial localized scleroderma. Systematic analyses of central nervous system imaging findings and their clinical associations in children are lacking. Here, we aim to characterize neuroimaging findings and associated neurological symptoms in these conditions. Methods: Neuroimaging and neurological symptoms of children evaluated at our institution with a diagnosis of PRS or ECDS were retrospectively reviewed. Laterality, location, stability, and number of lesion(s) were evaluated, as was the presence of susceptibility lesion(s) and contrast enhancement. History of seizures or headaches was noted. Results: From 2003 to 2019, 80 patients with PRS or ECDS were followed at our institution. Neuroimaging was completed in 73 and found to be abnormal in 25. In 12 (48%) of these 25 cases, headaches and/or seizures were present. In the vast majority of these cases (22/25, 88%), lesions were ipsilateral to skin findings. White matter was involved in 19 (76%) patients. MRI abnormalities preceded a rheumatological diagnosis in 7 (28%). Susceptibility lesions were noted in 11 (44%), and 8 (73%) of these patients endorsed a history of headaches. Most lesions were in the supratentorial compartment, did not enhance, and were stable at 1-year follow up imaging. Of those with progression, susceptibility findings were present at baseline. Conclusions: Neuroimaging findings in pediatric PRS and ECDS are often supratentorial, stable, unilateral, and ipsilateral to skin findings, and they can precede cutaneous findings.
