Copyright © 2020 by S. Karger AG, Basel.An 11-month-old full-term female infant was referred to the hematology clinic due to marked anemia and neutropenia. She was almost exclusively breastfed and rejecting all trials for supplementary food including artificial formulas. Bone marrow aspirate revealed cytoplasmic vacuolization in precursors of the myeloid and erythroid series with significant dysgranulopoiesis and dyserythropoiesis and ringed sideroblasts. Flow cytometry analysis revealed increased hematogones with aberrant loss/downregulation of CD33 on granulocytes and monocytes (sign of dysmyelopoiesis). Laboratory investigation revealed low serum copper and ceruloplasmin. Administration of a multivitamin including a high concentration of copper for only 1 week improved her hemoglobin and absolute neutrophil count up to 1.9 × 103/µL, then dropped to 0.3 103/µL after she stopped taking the copper multivitamin. Her blood counts improved till total normalization and up to the time this report is issued. The probable role of unrecognized copper deficiency in causing anemia in infants more than 6 months of age is discussed, and the importance of serum copper examination in refractory anemia and neutropenia is emphasized. This case shows that copper deficiency should be an integral part of the differential diagnosis of refractory anemia including sideroblastic anemia and dysplasia. To the best of our knowledge, no such case has previously been described in the literature. Copyright © 2020 by S.

Here, we report a case of a 71-year-old male patient with metastatic CRPC along with BRCA2 and PTEN mutations. As per the genomic findings of the Foundation One report, FDA-approved therapies were available for other tumor types, such as olaparib for the loss of BRCA2 and everolimus for the loss of PTEN exons 2-9. These findings were confirmed in another novel phenotypic assay that revealed the sensitivity of olaparib and carboplatin combination therapy. After 4 cycles, our patient achieved a partial response along with a good performance status. Copyright © 2020 by S. Karger AG, Basel.A 71-year-old woman presented to a nearby hospital with an occipital scalp ulcer with exudate. Thoracoabdominal enhanced computed tomography (CT) was performed due to suspected cancer. The imaging results showed tumors in the pancreatic tail and at multiple sites in the lung, whereupon she was referred to our hospital for further investigation. Histological analysis of the occipital scalp ulcer and the pancreatic tumor led to the diagnosis of pancreatic adenocarcinoma with cutaneous metastasis and multiple lung metastases. Combination chemotherapy (gemcitabine and nab-paclitaxel) was started, and about 4 months later the patient experienced right lower back pain. Abdominal CT showed partial sclerosis of the right iliac bone and multiple spinal lesions, which were diagnosed as multiple bone metastases. Narcotic analgesia was started for the right lower back pain. Since then, FOLFIRINOX has been introduced as second-line chemotherapy against tumor growth, and treatment has been ongoing for 10 months since the initial chemotherapy. Pancreatic cancer is a rapidly growing cancer and can show early metastasis to other organs, lymph node metastasis, and peritoneal dissemination; therefore, the prognosis of pancreatic cancer is very poor. Cutaneous metastasis from pancreatic cancer is rare, and only a few cases have been reported. Here, we report an unusual case of pancreatic adenocarcinoma with cutaneous metastasis and multiple lung and bone metastases. Copyright © 2020 by S.

Understanding the side effects associated with these medications is an important part of managing our patients. Although fatigue, rash, and diarrhea are commonly reported side effects, it is important to be cognizant of rarer ones, such as neuropathy. Amongst the different neurological toxicities that have been reported in the literature, Guillain-Barré-like neuropathies are quite rare. However, the occurrence of such neuropathies in a patient can be life threatening. The problem this poses in treating cancers such as melanoma is that it eliminates an effective class of medication available to the patient, which can ultimately affect their prognosis. We present a case of a 65-year-old female with unresectable metastatic melanoma who developed Guillain-Barré-like neuropathy after two doses of pembrolizumab. Her clinical course was complicated by three separate hospitalizations over 3 months due to recurring bouts of neuropathy, which resulted in a significant decline in performance status and delay in subsequent treatment of her melanoma. Her prolonged recovery eventually resulted in progression of her melanoma nearly 1 year later, while off therapy. Instead of discontinuing immunotherapy completely, she agreed to a re-challenge with ipilimumab. After one dose, her melanoma regressed and continues to show a sustained response nearly 1 year after treatment without any signs of relapse in her neuropathy. Guillain-Barré toxicity resulting from immune checkpoint inhibition poses a difficult challenge to an oncologist who is determining the next line of treatment for patients with unresectable metastatic melanoma that have progressed while off therapy and who have no targetable mutations. Our case raises the question of whether a re-challenge with a different class of immunotherapy agent is a reasonable option. Copyright © 2020 by S. Karger AG, Basel.Cancer-related pain is a very prevalent problem in all stages, with 10% of patients requiring invasive techniques for adequate pain management. Ganglion impar neurolysis has been used in the treatment of pelvic-perineal pain with efficacy and rare complications, but only a few case or series reports in cancer patients have been published. We report the case of a patient presenting with an ovarian carcinoma (FIGO stage IIIC), who had several disease relapses at the colorectal transition and need for palliative colic prosthesis. She presented later with anorectal pain associated with a rectovaginal fistula, which had an important impact on the activities of her daily life. She was submitted to two ganglion impar neurolyses, which resulted in improved pain control for a total of 5 months, an important improvement in her quality of life, and reduction of opioid consumption. The authors aim to alert to the importance of pain control and to address the fourth step of the WHO analgesic ladder as an option for cancer patients, including palliative patients.
