Superficial CD34-positive fibroblastic tumor is an infrequent soft-tissue tumor characterized by a lesion located in the subcutaneous fascia without affecting the soft or deep muscle planes. Its incidence is unknown; therefore, it represents a diagnostic challenge for both the surgical oncologist and pathologist. Given its high risk of local recurrence, extensive surgical resection is the recommended treatment modality. This is the first report of this rare entity in Latin-America.

Gangliocytic paraganglioma (GP) (nonchromaffin paraganglioma, paraganglioma) is a morphologically distinct tumor most commonly occurring in the second part of the duodenum in the proximity of ampulla of Vater. We herein, present a case report of appendiceal mass in a 16-year-old male who presented with recurrent right iliac fossa pain and steno sing cecal tumor on CT abdomen. He underwent right hemicolectomy and histopathological examination of appendix showed infiltration of appendiceal wall with gangliocytic paraganglioma. To our knowledge this is the first reported case of gangliocytic paraganglioma of appendix in our area.

Pediatric cancer overall survival has increased due to improvements in treatment. However, long-term adverse effects are a challenge for this population. Secondary myeloid neoplasm (MN) is one of the complications of solid tumor treatment. Therapy-related myeloid neoplasms (t-MN), therapy-related acute myeloid leukemia (t-AML), and therapy-related myelodysplastic syndrome (t-MDS) are the most common events. The aim of this study was to report a large pediatric sample and the relevance of t-MN after pediatric solid tumor therapy. We conducted a retrospective study between 2000-2016 in a cohort of pediatric patients treated for solid tumors who developed a secondary MN by medical records review and analysis. Seven from 2178 pediatric patients who were previously treated for solid tumors, were diagnosed with t-MN in a reference cancer center in Brazil. The median age at primary tumor diagnosis was 12.8 years old. Osteosarcoma, atypical primitive neuroectodermal tumor (PNET), Ewing sarcoma, and retinoblastoma were the most frequent solid tumors associated with t-MN. Three patients had a story of familiar cancer, and one patient with osteosarcoma had Li-Fraumeni syndrome confirmed. The median latency period to secondary MN was ten months and the prevalence rate was 0.32%. Two patients developed t-MDS and five, t-AML. All these patients received cytotoxic agents’ high doses that may have been associated with t-MN development. t-MN initial control, as well as unfavorable cytogenetic abnormalities, may have contributed to the poor outcome. We described the rarity of t-MN related to previous solid tumor therapy in a large pediatric sample in a Brazilian Cancer Center and their poor prognosis.

Patients with Philadelphia-negative myeloproliferative neoplasms (PN-MPN) are at a higher risk for venous thrombosis. Thromboelastometry may prove efficient to evaluate the patient’s thrombotic risk. In this study, based on data from 114 patients with PN-MPN from a single center in Greece, hemostatic profile was assessed with routine coagulation tests, Rotational Thromboelastometry (ROTEM® ), and Platelet Function Analyzer (PFA)-100 and correlated with clinical, laboratory, treatment characteristics, gene mutations and polymorphisms of poly (ADP-ribose) polymerase-1 (PARP-1)

A 51 year old female was referred to our dermatology clinic for a rapidly growing lump on head of 6 weeks duration. On examination we observed a 15 cm diameter erythematous crusted tumor on the forehead with significant bilateral cervical lymphadenopathy. An excision biopsy of the tumor revealed a malignant high grade diffuse undifferentiated infiltrating neoplasm involving the skin and subcutaneous tissue.

Thyroid tissue samples of 200 patients who underwent total thyroidectomy, near total thyroidectomy and subtotal thyroidectomy for surgical management of multinodular goiter were designed our study. The surgical procedures were performed between January 2016 and December 2018 in general surgery department MUST University. Preoperative ultrasound-guided fine needle aspiration cytology and the postoperative surgical specimens were delivered to pathology lab at MUST University 6th of October city, Giza. Patients with thyroid neoplasms, thyroiditis, toxic and recurrent goiter were excluded from the study. Personal and demographic data were collected and analyzed. Postoperative clinical complications and incidental neoplasms were evaluated. All the patients were followed up over 1 year for expected clinical complications, recurrence of goiter and appearance of neoplasms.

Recurrence of a mucinous ovarian neoplasm after resection is unusual but this does happen. If possible, a repeat surgical removal of recurrent disease is the treatment of choice. The results of a repeat intervention are poor. A review of our results of treatment of recurrent mucinous ovarian neoplasms was performed.

Hydatid disease of the pancreas is a rare condition, with an incidence of less than 1%. Establishing diagnosis may be difficult because clinical and imaging findings are similar to other more commonly encountered cystic lesions of the pancreas. We present a case of isolated Hydatid cyst in the tail of pancreas which masquerading as the mucinous cystic neoplasm of the pancreas.
