We present a case report of a patient with a rare high-grade transformation of an acinic cell carcinoma (ACC) of the parotid gland, who developed Cushing's syndrome (CS) as a result of ectopic secretion of adrenocorticotropic hormone by the tumour. The hypercortisolism was successfully treated with metyrapone, and the ACC was treated with local radiotherapy and a combined six cycles of gemcitabine and cisplatin, having achieved a partial response to the tumour. A multidisciplinary approach and combined medical treatment with radiotherapy and were essential for disease control and CS management...

Primary breast angiosarcoma is an extremely rare disease with a poor prognosis. Primary angiosarcoma is distinct from secondary angiosarcoma, which usually occurs in patients who have been previously treated for breast cancer. The low incidence of primary breast angiosarcoma has hindered the elucidation of its etiology and potential therapies. Here, we report a case of a patient with primary breast angiosarcoma who experienced recurrence after surgery. The tumor was refractory to systemic treatments, and the patient died 18 months after the surgery...

Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive intermediate soft tissue neoplasm that occurs in the dermis. DFSP generally occurs in young to middle-aged adults and rarely in infancy. Because of its extreme rarity, DFSP is difficult to diagnose and treat, especially when it occurs in infancy. In this paper, we reported a case of infantile DFSP in which we performed additional wide resection with a 3-cm horizontal margin for a mass that had previously undergone unplanned excision. No tumor recurrence has been seen for 3 years postoperatively...

Here, we present a 69-year-old female with advanced neuroendocrine carcinoma (NEC) of colon with multiple liver, bone, and kidney metastases who developed Trousseau's syndrome. The patient received etoposide plus cisplatin (EP) as the first-line therapy; however, after single administration of EP, she developed the severe lower-limb edema and EP was considered to be intolerable. Etoposide plus carboplatin was administered as the second-line therapy and after 3 cycles of administration, the progressive disease (PD) was confirmed and 5-fluorouracil + leucovorin + irinotecan (FOLFIRI) plus ramucirumab was administered as the third-line therapy...

Capecitabine is an orally administered fluoropyrimidine carbamate antineoplastic agent, widely used to treat different tumor types. Eye toxicity is not well established with this type of drug. Here, we report the case of a 57-year-old man with a low rectal cancer whose vision decreased 3 weeks after starting a daily treatment of capecitabine and radiotherapy. After eliminating all other diagnoses, toxicity of antineoplastic agents remains the most likely hypothesis, making it the first case of vision loss induced by this capecitabine...

In recent years, both the number of patients with breast cancer and those with associated brain metastases (BMs) have increased. Human epidermal growth factor receptor 2 (HER2)-positive breast cancer has a high BM frequency. The prognosis of BM from breast cancer is poor, and establishing effective treatment for this disease is essential. We report a HER2-positive patient with multiple BM and right-eye blindness due to pituitary metastasis. She responded promptly to trastuzumab deruxtecan (T-DXd) in the 5th line of treatment, which shrunk the tumors and restored vision...

Chemotherapy-related encephalopathy is a rare but severe side effect of cancer therapy. Few reports exist on the course of encephalopathy due to 5-fluorouracil (5FU)/carboplatin treatment. Here, we report on a patient in his 70s, who received first-line palliative treatment with carboplatin followed by continuous infusion of 5FU against a metastasized cancer of the base of the tongue. During the first 5FU infusion, the patient developed a coma with sudden onset. In contrast to earlier reports of 5FU-induced encephalopathy, serum ammonium levels were near-normal, despite a slightly increased bilirubin...

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer associated with higher rates of relapse and mortality compared to other subtypes. Chemotherapy has been a mainstream treatment approach for TNBC due to the lack of therapeutic targets. Recent advances have led to the introduction of novel agents against specific patients with programmed death-ligand 1 (PD-L1)-positive TNBC who harbor germline BRCA mutations. However, some patients who respond to PD-L1 or poly (ADP-ribose) polymerase PARP inhibitors often develop resistance...

Solitary fibrous tumors (SFTs) are soft tumors (mesenchymal origin) that most likely develop from adult mesenchymal stem cells. SFTs are not common in the head and neck region, and the characteristics of tumors in this location are unclear. The present study describes the clinicopathological findings of 2 cases of SFTs arising in the parotid gland and buccal space, presenting as salivary gland tumors. The first case is a 76-year-old man presenting with a painless tumor on the right parotid gland who subsequently underwent partial superficial parotidectomy...

We present a patient with recurrent mantle cell lymphoma (MCL) who was treated with zanubrutinib, a Bruton's tyrosine kinase inhibitor. He subsequently developed bilateral cystoid macular edema (CME) in both eyes. This is the first report of CME in a patient with MCL who was treated with zanubrutinib. CME was refractory to topical corticosteroid therapy, but sub-Tenon's steroid injections and holding off zanubrutinib managed to decrease the CME. Treatment managed to prevent further vision loss but did not restore lost vision...

Desmoplastic fibroma is a rare primary benign bone tumour that typically affects the long bones, mandible, and pelvis. It has a similar local aggressiveness to soft tissue fibromatosis. It rarely involves the small bones of the hand. We describe an extremely rare case of desmoplastic fibroma of the proximal phalanx of the hand in a patient who presented with an aggressively enlarging but painless mass on the left ring finger. Radiological features suggested malignancy; however, an initial biopsy revealed fibrotic tissue...

We report a 58-year-old male with a histopathologically proven grade 2 (G2) pancreatic neuroendocrine neoplasm and multiple abdominal node metastases by use of a laparoscopic pancreatic body and tail resection procedure, plus abdominal lymph node dissection. A primary pancreatic tail neuroendocrine tumor sized 20 × 25 mm was detected by contrast-enhanced computed tomography, somatostatin receptor scintigraphy (SRS), and fluorodeoxyglucose positron emission tomography (FDG-PET) examinations and pathologically diagnosed as a pancreatic neuroendocrine tumor (PNET, G2) based on positive immunostaining for somatostatin receptor (SSTR) type 2...

We encountered a case in which the general condition of a patient receiving cabazitaxel worsened with concomitant use of clarithromycin. Cabazitaxel is metabolized mainly by CYP3A4, and the frequency of adverse events is known to increase with increasing exposure. Although these drugs are not often quantified in daily practice, we quantified them because we considered it possible that the blood concentration of cabazitaxel had increased due to CYP3A4 inhibition of clarithromycin and that cabazitaxel-related adverse events had occurred...

Langerhans cell histiocytosis (LCH) is a rare neoplastic disease characterized by infiltration of histiocytes and dendritic cells into body organs. While treatment is better established in pediatrics, there is still no consensus on therapy in the adult population. Imatinib has shown promising results in some case reports and a small clinical trial. We present here a fifty-nine-year-old patient with LCH in the lung, liver, and bone who responded well to an imatinib dose of 100 mg daily. Her symptoms improved within 3 months of treatment, and subsequent positron emission tomography-computed tomography (PET/CT) showed resolution of 18F-fluorodeoxyglucose (FDG)-avid lesions...

MUTYH-associated polyposis syndrome is an uncommon, autosomal recessive colorectal polyposis syndrome caused by biallelic inactivation of MUTYH . Most patients present with multiple colorectal polyps. However, other primary tumor sites have been described as less frequent. In this report, we describe the case of a young patient with a germline biallelic pathogenic MUTYH mutation with three different primary tumors. We focused on a metastatic gastric adenocarcinoma that presented with complete bowel obstruction secondary to extensive peritoneal carcinomatosis and achieved complete response upon treatment with immunotherapy...

Cerebral toxoplasmosis is an opportunistic infection that, by itself, is difficult to differentiate from cerebral neoplasms by conventional neuroimaging. It rarely occurs concurrently in patients with a primary brain tumor but when it does, it makes diagnosis and management more difficult. This is a case of a 28-year-old female, diagnosed with a right frontal pleomorphic xanthoastrocytoma with several recurrences, treated with surgery, radiation, and chemotherapy. Three years from diagnosis, the patient was readmitted for generalized body weakness, fever, and a decrease in sensorium...

We present a rare phenomenon of a soft tumor hanging on the woman's left upper arm that underwent necrosis from the distal aspect during chemotherapy for pancreatic cancer. The benign tumor, pedunculated lipofibroma, originally had normal color for 10 years and then became necrotic when she was treated with gemcitabine and nab-paclitaxel. Necrosis stopped in conjunction with chemotherapy cessation. Dermatologists must remember that nab-paclitaxel could develop necrosis of a skin tumor.

This article describes the case of a 73-year-old patient with grade 3 immune checkpoint inhibitor (ICI)-induced enteritis. Five different immunosuppressive agents (glucocorticoids, high-dose infliximab, methotrexate, mycophenolate mofetil, and vedolizumab) were administered, however, with no clinical or radiographical benefit. A laparotomy was performed, as the patient showed signs of intestinal obstruction, with a segmental resection of the ileal loop. Biopsy results showed multiple fibrotic strictures. The current treatment guidelines for ICI enterocolitis only include drugs as a treatment option...

Enfortumab vedotin (EV) is an antibody-drug conjugate and a promising agent for metastatic urothelial carcinoma (mUC). However, evaluations in end-stage renal disease patients undergoing hemodialysis are unreported. Here, we report such a case. A 74-year-old woman with mUC, on hemodialysis for complete urinary tract extirpation, was diagnosed with multiple pulmonary metastases after treatment with gemcitabine-carboplatin followed by pembrolizumab. As third-line therapy, she received a standard dose of EV. She achieved complete response after 2 cycles without grade 3 or higher adverse events, demonstrating the utility of EV in this setting...

Pulmonary veno-occlusive disease (PVOD) is an extremely rare condition in oncology practice. Although PVOD is clinically similar to pulmonary arterial hypertension, the conditions differ in terms of pathophysiology, management, and prognosis. This report discusses the case of a 47-year-old woman who developed dyspnea and fatigue after high-dose cyclophosphamide chemotherapy and autologous hematopoietic stem cell transplantation for relapsed lymphoma. The patient exhibited tachycardia, tachypnea, and hypotension, but other findings in the physical examination were unremarkable...
