Low Malignant Potential

Urachal mucinous cystic tumours are rare pathological findings with only 23 previously reported cases in the literature. We present the case of a 54-year-old man with an incidentally found urachal mucinous cystic tumour laparoscopically excised. With its known potential to cause pseudomyxoma peritonei, complete surgical excision is important. Long-term cystoscopic and radiological surveillance is also required.

Summary Introduction: Solid pseudopapillary tumor of the pancreas (SPTP) is a rare neoplasm of low malignant potential with uncertain behavior, diagnosed mainly in young women. Method: Our report comprises a series of cases of SPTP reviewed retrospectively, highlighting clinical, tomographic and immunohistochemical features, treatment performed and outcomes. Results: Thirteen patients were found to have pancreatic [solid] masses on computed tomography scan measuring a mean diameter of 8.8 cm. All patients underwent complete surgical excision. Immunohistochemistry confirmed diagnosis in all cases. Conclusion: SPTP occurs more frequently in young women. Diagnostic suspicion lies on the finding of a bulky, solid and cystic pancreatic mass. Imaging findings might provide diagnostic information before resection. Conservative approaches can be used in selected cases and survival rates are usually excellent following complete resection.

AbstractNeoplasms of the urachus are exceedingly rare, representing 0.17% of all bladder cancers. The mucinous cystic tumor of low malignant potential (MCTLMP) subtype is particularly rare with just 25 previous cases reported in the literature. Although rare, MCTLMPs are important to identify due to potential devastating complications and good cure rates with surgical removal. We present a 43 year old female with a nuanced constellation of comorbidities and confirmed MCTLMP following a workup for abdominal pain and irritative lower urinary tract symptoms. Notably, this tumor did not change in size over a 3-year course of serial imaging prior to surgical excision. This urachal MCTLMP represents roughly the 26th and one of the smallest of its subtype reported in the literature. This case illustrates the diagnosis and management of this rare urachal MCTLMP. Individual patient medical history, clinical considerations, and neoplasm characteristics are examined. Although rare, the potential for increased malignancy and potential complications necessitates surgical management and further investigation by the academic community.

Granular cell tumour (GCT) is a rare soft tissue lesion which many consider to have malignant potential of yet unknown aetiopathogenesis. Oral GCT lesions may occur in an area of leucoplakia and are predominantly present on the tongue. This case study highlights an uncommon presentation of this condition located on the buccal mucosa and illustrates the need for meticulous evaluation of suspicious lesions. Due to the malignant risk associated with GCT lesions, it is important to make the correct diagnosis and ensure complete surgical excision for these cases. Ongoing long-term follow-up is also indicated to monitor for recurrence or malignancy.

Peritoneal Spread

Urachal mucinous tumors are rare neoplasms with behaviour that can range from relatively benign to malignancy that can spread distantly or throughout the peritoneum as pseudomyxoma peritonei or peritoneal carcinomatosis. Here we describe a unique case of urachal mucinous cystic tumor of low malignant potential confined to an intact cyst at the dome of the urinary bladder, without rupture or peritoneal spread. The urachal mucinous tumor was an incidental finding on a staging CT scan performed for sigmoid colon adenocarcinoma. We believe that this case illustrates a potential diagnostic pitfall which could have prognostic and therapeutic implications. Due to the intestinal phenotype of these neoplasms, a urachal tumor of low malignant potential could be mistaken for metastatic spread from a colonic adenocarcinoma in the rare situation such as this case, where the two neoplasms occur concurrently.

The Right

A 63-year-male had painless, progressive, yellowish-pink, immobile conjunctival mass with prominent feeder vessels in the right eye of 1-year duration. The rest of the ophthalmic examination was unremarkable. MRI showed no extension into orbit or extraocular muscles. An excision biopsy with the amniotic membrane patch was performed. Histopathology confirmed inflammatory myofibroblastic tumour (IMT) with SMA and calponin positivity on immunohistochemistry. Complete surgical excision, amniotic membrane, and oral steroids provided long-term relief from recurrence. The conjunctiva is a rare site for IMT, and IMT should be kept in the differentials for atypical cases of ocular surface neoplasia.

Neuroendocrine Carcinomas

Thymic neuroendocrine carcinomas (carcinoid) are rare tumors. They have malignant potential, the capacity for distant metastasis, and often present with associated endocrinopathies. This report describes a patient who was diagnosed with thymic carcinoid and Cushing syndrome at age 19 that, despite complete surgical excision of his tumor, developed local recurrence with distant metastases to his brain, lungs, and bone. We discuss the evolution of this patient's illness as well as the therapies used in his care. Due to the nature of these tumors to recur both locally and distant, the importance of aggressive surgical management is emphasized. We also discuss the role of adjuvant therapy, which in our case consisted of chemotherapy, radiotherapy, and several new therapies including an antiangiogenesis agent and a tyrosine kinase inhibitor.
