Abstract Introduction/Objective Histiocytic sarcoma (HS) is rare (<1% of hematolymphoid neoplasms), and can present extranodally as disseminated disease. Immunophenotypically, the cells express CD163, CD68, lysozyme and CD45. HS often occurs as a secondary event following B-cell lymphomas, acute lymphoblastic leukemia or acute myeloid leukemia (AML) typically with monocytic differentiation retaining the same molecular/cytogenetic abnormalities as the primary tumor. Results Our patient, a 47 year old male was diagnosed with myeloid sarcoma (MS) following FNA of a new neck mass. A bone marrow biopsy revealed AML without monocytic differentiation. Flow cytometric findings of both marrow and neck mass were similar (positive for CD34, CD117, CD33, CD11b, CD13, CD15, CD64, CD7; negative for CD4, CD14, CD56). Karyotypic and FLT3 ITD mutation analysis were normal. CNS involvement was diagnosed 2 months later, while a marrow biopsy (status post therapy) confirmed resolution of AML. A hypermetabolic left perinephric mass noted by PET CT, when biopsied, showed large epithelioid polygonal cells with amphophilic cytoplasm and atypical vesicular nuclei (positive for CD68, PU.1; negative for LCA, CD163, CD34, CD4, pankeratin). A diagnosis of atypical epithelioid neoplasm suggestive of HS was rendered, although negativity for LCA and CD163 was unusual. No treatment was given for HS. A month later, the patient presented with a cheek mass diagnosed again as being suggestive of HS. His AML also relapsed. Next-generation sequencing (37 genes including BRAF) from both marrow and tissue samples detected the presence of a nonsense mutation in exon 7 of WT1 (p.Ser169). Conclusion Our case appears to be the first reported one of disseminated HS preceded by MS and concomitant AML, lacking monocytic differentiation. The findings overall support the hypothesis of origin as being from a common progenitor cell differentiating along both myeloid and histiocytic/other cell lineages at different time points.

AbstractCryptococcosis is a fungal infection that is rarely reported in patients without human immunodeficiency virus (HIV) infection, especially when the central nervous system (CNS) or pulmonary system is not involved. We report a case of isolated colonic cryptococcosis without disseminated disease in a 64-year-old immunocompetent woman without HIV infection who presented with chronic diarrhea and no episodes of fever or weight loss. The diagnosis was based on histopathology examination. Furthermore, we performed a literature review showing that few reports have been published so far and in the case of colonic cryptococcal infection, the prognosis is favorable among HIV-uninfected patients.

Abstract INTRODUCTION Intracranial malignant germ cell tumours (iGCT) are rare brain tumours mainly diagnosed in children and younger adults. MATERIAL AND METHODS A retrospective analysis was performed by chart review of patients treated for iGCT in the northern and central region of Denmark. Teratoma only patients were not included in the study. RESULTS 20 patients with iGCT were diagnosed from 2008–2019 in Western Denmark. The cumulative incidence was 1.05 per 100.000. The yearly incidence was 0.1 per 100.000. Mean age at diagnosis was 18 years (range 8–36 years), 17 were males and 3 were females. 13 patients presented with germinoma and 7 patients with non germinomateous germ cell tumours (NGGCT). Three patients had disseminated disease, two with germinoma and one with NGGCT. All patients had received radiotherapy and 18 patients were treated with multidrug chemotherapy including platinum and etoposide before irradiation. Two patients experienced recurrent disease, both non disseminated at diagnosis, one patient with germinoma and one patient with NGGCT. Both received salvage treatment including high dose chemotherapy with stem cell transplantation and reirradiation. Two NGGCT patients died, one patient after development of an anaplastic astrocytoma in the radiation field five years after radiotherapy and one patient after intracranial hemorraghe 18 months after salvage treatment for recurrent disease. Overall survival was 90%, 100% for GCT and 71% for NGGCT. CONCLUSION The outcome of patients with iGCT in Western Denmark was comparable to the literature. A nationwide study of epidemiology and outcome of iGCT in Denmark is planned.

In this paper, we present a multicentre record-based descriptive study used to estimate the incidence and characterize the spectrum of confirmed bacille Calmette–Guérin (BCG) vaccine-related disease among children in Oman. This study included all children (age ≤ 14 years) who had culture and/or polymerase chain reaction (PCR)-confirmed BCG disease from January 2006 to December 2018, as identified from Central Public Health Laboratory data and International Classification of Diseases coding of an electronic patient information system. In total, 88 children confirmed to have BCG disease were included in the study, making an average incidence of 9.2 cases per 100,000 vaccinated neonates. The males comprised 65.9%, Omanis 93.2%, and the median age of presentation was 4 months in children with BCG disease. The most common type of disease was BCG abscesses (72.4%). Children with immunodeficiency and those presenting within 6 months were found to have a more severe and disseminated disease. In total, 28 children had immunodeficiency. The age of presentation and type of BCG disease was significantly associated with immunodeficiency status. The majority of cases required therapy (both medical and surgical) and recovered well. The incidence of laboratory-confirmed BCG vaccine-related disease was low in Oman supporting continuing the use of the BCG vaccination practice at birth.

Abstract Background Kaposi’s sarcoma is an uncommon complication in renal transplant patients, and typically presents with cutaneous lesions on the lower extremities. Penile involvement has been reported only rarely. Management of cutaneous-limited disease is primarily reduction of immunosuppression and conversion to an mTOR-inhibitor, whereas the treatment of disseminated disease in transplant patients is more variable. Case presentation A 75-year-old male, originally from Somalia, received a deceased-donor kidney transplant for diabetic and hypertensive nephropathy. Seven months post-transplant he presented with lower limb lesions, oedema and bilateral deep vein thromboses. He then developed a fast-growing painful lesion on his penile shaft. A biopsy of this lesion confirmed KS, and a PET scan demonstrated disseminated disease in the lower extremities, penis and thoracic lymph nodes. His tacrolimus was converted to sirolimus, and his other immunosuppression was reduced. He was treated with single agent paclitaxel chemotherapy in view of his rapidly progressing, widespread disease. The penile lesion completely resolved, and the lower extremity lesions regressed significantly. His kidney allograft function remained stable throughout treatment. Conclusion This case illustrates a rare presentation of an uncommon post-transplant complication and highlights the need for a high index of suspicion of KS in transplant patients presenting with atypical cutaneous lesions. It serves to demonstrate that the use of single agent paclitaxel chemotherapy, switch to an mTORi and reduction in immunosuppression where possible produces excellent short-term outcomes, adding to the body of evidence for this management strategy in disseminated Kaposi’s sarcoma.

Coccidioidomycosis is a fungal infection of the Western hemisphere that is endemic to the soil in areas with limited rainfall. Human and animal infections result with inhalation of arthroconidia. Most often, this is an asymptomatic event. When illness occurs, it is primarily a pneumonic presentation. A small minority of infections eventuate in disseminated disease. Predominately, this presents as meningitis or osteoarticular or integumentary disease. Treatment may not be required for the mildest illness. Azoles are commonly prescribed. Severe infections may require amphotericin B.

Nuclear protein in testis (NUT) carcinoma represents a highly aggressive, poorly differentiated carcinoma that is genetically defined by rearrangement of NUT gene. The histomorphological appearance ranges from entirely undifferentiated carcinoma to carcinoma with prominent squamous differentiation. NUT carcinoma can display neuroendocrine features. Although it is typically distributed along the midline axis, it may manifest in nonmidline locations. The majority of patients develop rapidly disseminated disease. We illustrate 2 cases of NUT carcinoma, one located in the lung, which closely resembled a neuroendocrine carcinoma, and the other one with assumed lung origin demonstrating metastatic dissemination with diffuse bone involvement, which was clinically first suspected to be a hematological malignancy. Due to its undifferentiated nature, NUT carcinoma may be confused with many entities. NUT immunohistochemistry is considered to be sufficient for the diagnosis. Fluorescence in-situ hybridization analysis and next-generation sequencing are currently used to confirm the diagnosis.
