T-Large Granular Lymphocytic Leukemia with Hepatosplenic T-Cell Lymphoma? A Rare Case of Simultaneous Neoplastic T-Cell Clones Highlighted by Flow Cytometry and Review of Literature.

Lymphoproliferative diseases are a heterogeneous set of malignant clonal proliferations of lymphocytes. Despite well-established diagnostic criteria, the diagnosis remains difficult due to their variety in clinical presentation and immunophenotypic profile. Lymphoid T-cell disorders are less common than B-cell entities, and the lack of a clear immunophenotypic characteristic makes their identification hard. Flow cytometry turned out to be a useful tool in diagnosing T-cell disorders and to resolve complicated cases, especially if the number of analyzable neoplastic cells is small. We present a case of a 55-year-old man with simultaneous lymphoproliferative neoplastic T-cell clones, one αß and the other γδ, identified and characterized by flow cytometry (FC), exploiting the variable expression intensity of specific markers. However, the patient's rapid decline made it impossible to define a differential diagnosis in order to confirm the identity of the γδ clone, which remains uncertain. This case is added to the few other cases already documented in the literature, characterized by the co-existence of T-large granular lymphocytic leukemia (T-LGLL)-αß and T-LGLL-γδ/Hepatosplenic T-cell lymphoma (HSTCL). Our case underlines the key role of sensitive diagnostic tools in the assessment of potential relationship between the diagnosis, prognosis, and treatment in the two pathologies.

Gonadal vein leiomyosarcoma, from clinical practice to a literature review: surgical, oncological and histopathologic correlation.

BACKGROUND AND AIM: Vascular leiomyosarcomas are rare and generally originate from the muscular wall of the inferior vena cava. Leiomyosarcomas originating from the wall of the gonadal veins are rare and just about ten cases are described in literature. In the present paper, we have described a case of a LMS originating from the left gonadal vein. METHODS: A 44-year-old woman presented in March 2020 pain symptoms at the level of the left renal lodge. The subsequent CT and the biopsy confirmed the diagnosis of G2 grade LMS. The mass was then removed en bloc from the posterior and inferior pancreatic plane, from the aortic plane and from the retroperitoneal plane, post chemoteraphy. RESULTS: Pathologic report revealed a typical leiomyosarcoma, moderately differentiated G2 with minor dedifferentiated areas of pleomorphic leiomyosarcoma. CONCLUSIONS: The LMSs originating from gonadal veins represent an uncommon oncologic challenge. The radical en bloc excision represents the therapeutic gold standard.

Diffuse Leukoplakia of the Bladder Ostium-Sparing in Patient Treated with Leuprorelin for Breast Cancer.

CASE: A 55-year-old woman came to our attention in April 2020 referring haematuria, frequency and urgency. The patient referred previous treatment with leuprorelin 3.75 mg/2 ml for breast cancer three years ago. Urine culture was performed and resulted always negative for pathogens. Cystoscopy revealed a whitish plaque lesion on the fundus, dome, trigone, and left lateral wall of the bladder. Histology of the biopsy confirmed the diagnosis of leukoplakia of the bladder. The plan is to follow her up repeating a cystoscopy every three months and biopsy in 6 months. Literature search revealed very little information on pathogenesis and prognosis of this condition due to its rare occurrence. The main objective of our case study was to describe individual situation of a woman affected by diffuse leukoplakia of the bladder ostium-sparing with a previous treatment with leuprorelin 3.75 mg/2 ml for breast cancer and to show safety of follow-up by cystoscopy and biopsy. CONCLUSIONS: We showed a case of a woman treated with leuprorelin and with diffuse leukoplakia of the bladder. We support the recommended long-term follow-up and surveillance based on the literature review by cystoscopy with or without biopsy.
