Abstract Background: Small round blue cell malignancies are rare and highly aggressive tumors that are commonly located in the soft tissues or axial bones of the bone or trunk and are particularly rare in the kidney. The common cause of ectopic ACTH syndrome is pulmonary neuroendocrine tumors, such as small cell carcinomas and carcinoid tumors. Here, we present an unusual case of ectopic ACTH syndrome and hypothyroidism caused by small round blue cell tumor of the right kidney.Case presentation: A 19-year-old girl presented with a history of right lumbar pain and discomfort for 2 months, aggravated for 2 days. Abdominal contrast-enhanced computed tomography and computed tomography angiography showed right suprarenal pole occupancy with subepithelial hemorrhage. Preoperative hormone levels including plasma total cortisol (PTC), adrenocorticotrophic hormone (ACTH) and thyroid hormone measurements were abnormal, indicating that the patient had Cushing syndrome and hypothyroidism. The patient underwent right radical nephrectomy. Histopathological analysis revealed a renal small round blue cell tumor (consistent with a primitive neuroectodermal tumor), with positive immunohistochemistry for CD99 and Ki67 (about 10%) and molecular pathology for EWSR1 gene fusions. PTC, ACTH and thyroid hormone returned to normal after surgery.Conclusions: We report a rare ectopic ACTH syndrome and hypothyroidism due to renal small round blue cell tumor. The clinical manifestation of renal small round blue cell tumor is non-specific and the diagnosis relies on pathological morphology, immunohistochemistry and fusion gene detection. At present, surgery combined with radiotherapy and chemotherapy is used in the treatment, but the prognosis is still not optimistic.

ABSTRACT Malignancies characterized histologically by high-grade monotonous small round blue cells (SRBCs) belong to a heterogeneous group of neoplasms often referred to as Ewing family of tumors. The most common molecular confirmation of these neoplasms is by fusions between EWSR1 gene on chromosome 22 and the ETS family of transcription factors, including FLI1 gene (11q24) and the ERG (21q22), that are implicated in the development of different tissues as well as cancer progression. In this article, we present a case of highly aggressive extraskeletal SRBC tumor involving the foot of a 24-year-old male with sole molecular findings of mutations in KAT6A, NAV3 and SMARCA1 genes with high expression of soft tissue markers (COL1A1, COL1A2, COL3A1) and MYC mRNA. To our knowledge, this unique mutational pattern has not previously been described in SRBCs.

Ewing sarcoma/Primitive Neuroectodermal Tumor (ES/PNET) is a malignant small round blue cell tumor of neuroectodermal origin that affects bones and soft tissue in children and young adults. ES/PNET is very uncommon in parenchymal organs. We report a case of primary adrenal PNET in a young female having pregnancy induced persistent hypertension. She underwent right adrenalectomy for a large adrenal mass. On histopathology, it was typical malignant round cell tumor (MRCT). Immunohistochemistry confirmed the diagnosis of ES/PNET with expression of CD99, FLI-1 and NKX2.2. Until now, only 38 cases of primary adrenal ES/PNET have been reported in the English literature with just 5 cases from India. Adrenal ES/PNET can be mistaken with other MRCTs like Non-Hodgkin lymphoma and neuroblastoma. Since the biology, treatment and prognosis of these tumors is entirely different, we emphasize that pathologists must be aware of this possibility and try to differentiate them using ancillary techniques.

Ewing’s sarcoma (ES) is a highly malignant, small, round cell tumor that originates from the primitive neuroectodermal cells. Primary ES commonly occurs in early childhood or adolescence. It may present with skeletal and extraskeletal forms. The extraskeletal form is rarely encountered in the head and neck region and is extremely rare in the sinonasal tract. This is a case report of sinonasal ES in a 13-year-old female patient who presented with a 7-month history of right nasal obstruction, anosmia, intermittent epistaxis, snoring, and hearing loss. Clinical examination revealed a right nasal mass pushing the septum to the left side and extending to the nasopharynx. Endoscopic biopsy and histopathological analysis showed a small blue cell tumor suggestive of ES. The patient was treated with surgery, radiotherapy, and chemotherapy. After a follow-up of 5 years, the patient remains recurrence-free with excellent functional status and quality of life.
