Malignant melanoma is a neoplasm of melanin-producing cells predominantly of cutaneous origin, which uncommonly develops within gut mucosa. We present the case of a 58-year-old woman with complaints ...of abdominal pain, loss of appetite and weight. Esophagogastroduodenoscopy revealed a gastric mass and systemic imaging demonstrated widespread nodal and bilateral adrenal gland involvement. Histopathology of the gastric mass confirmed primary malignant mucosal melanoma of the stomach. The patient received three cycles of Nivolumab but did not respond, and thus, was then offered best supportive care. Although infrequent, mucosal melanoma can arise from the gastrointestinal tract, and in contrast to the cutaneous form, advanced disease usually has a dismal prognosis and responds poorly to immune checkpoint inhibitors. Primary gastric melanoma is an aggressive disease that is diagnosed by exclusion after the differential diagnosis of metastasis from a cutaneous or unknown primary site has been conducted. If available, patients with treatment-naïve mucosal melanoma should be considered for enrollment in clinical trials.
COVID-19 infection resulting from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began to spread across the globe in early 2020. Patients with hematologic malignancies are supposed to ...have an increased risk of mortality from coronavirus disease of 2019 (COVID-19) infection. From Pakistan, we report the analysis of the outcome and interaction between patient demographics and tumor subtype and COVID-19 infection and hematological malignancy.
This multicenter, retrospective study included adult patients with a history of histologically proven hematological malignancies who were tested positive for COVID-19 via PCR presented at the oncology department of 5 tertiary care hospitals in Pakistan from February to August 2020. A patient with any known hematological malignancy who was positive for COVID-19 on RT-PCR, was included in the study. Chi-square test and Cox-regression hazard regression model was applied considering p ≤ 0.05 significant.
A total of 107 patients with hematological malignancies were diagnosed with COVID-19, out of which 82 (76.64%) were alive, and 25 (23.36%) were dead. The significant hematological malignancy was B-cell Lymphoma in dead 4 (16.00%) and alive group 21 (25.61%), respectively. The majority of the patients in both the dead and alive group were on active treatment for hematological malignancy while they came positive for COVID-19 21 (84.00%) & 48 (58.54%) p 0.020. All patients in the dead group were admitted to the hospital 25 (100.00%), and among these, 14 (56.00%) were admitted in ICU with a median 11 (6-16.5) number of days. Among those who had contact exposure, the hazard of survival or death in patients with hematological malignancies and COVID-19 positive was 2.18 (CI: 1.90-4.44) times and 3.10 (CI: 2.73-4.60) times in patients with travel history compared to no exposure history (p 0.001).
Taken together, this data supports the emerging consensus that patients with hematologic malignancies experience significant morbidity and mortality resulting from COVID-19 infection.
An intraductal papillary neoplasm involving the biliary tree is an unusual premalignant condition of epithelial origin, identified by its cystic dilatation of the biliary channels. Being a ...slow-growing tumor, surgery offers the best curative rate, especially in the setting of a low-grade disease. Here, we present a case of a localized, low-grade, intraductal papillary neoplasm of the bile duct (IPNB), residing in the liver, which was treated with resection of the liver lobe. The adjuvant treatment and prognosis highly depend upon the presence of dysplasia or a co-existent invasive malignancy. To the best of our knowledge, being a rare entity, this is the first case to be reported from Pakistan.
Abstract
BACKGROUND
Glioblastoma is the most common primary brain tumor in adults. The current standard of care is multimodal approach comprising of maximal safe surgical resection, post-operative ...radiation therapy (RT), and concurrent and adjuvant temozolomide (TMZ). To date, no published data are available for the outcome of this disease treated with standard of care in Pakistan. In this study results of concomitant chemoradiation with 5 days of temozolomide followed by temozolomide has been reported.
OBJECTIVE
To determine Progression Free Survival (PFS) and Overall Survival (OS) in patient’s receiving concomitant chemoradiation with 5 days of temozolomide followed by temozolomide in newly diagnosed GBM.
METHODS
Patients with newly diagnosed glioblastoma were assigned to receive concomitant chemoradiation with temozolomide (75mg/m2) 5 days per week on the days of radiation. After a 4-week break, patients then received monthly temozolomide (150-200mg/m2) 5-day schedule every 28 days.
RESULTS
From June 2011 to June 2016, 58 patients with newly diagnosed GBM were included in the study. Median age was 54 years, 71% (n=41) were male, whereas 29% (n=17) were female. 57% (n=33) underwent subtotal resection, 33% (n=19) had gross total resection while 10% (n=6) underwent biopsy only. About 64% (n=37) completed standard of care concomitant chemoradiation followed by monthly TMZ.36 % (n=21) completed only concomitant chemoradiation and were lost to follow. At a median follow up of 1 year, median PFS and OS was 8 and 13 months respectively with chemoradiation followed by TMZ. In subgroup analysis median PFS and OS benefit was more in patients who underwent maximal safe resection as compared to biopsy.
CONCLUSION
This study confirmed that PFS and OS benefit was more in patients who completed concomitant chemoradiation followed by monthly TMZ. OS benefit was almost similar with 5 days of TMZ as opposed with 7 days of TMZ as reported in international study.

Primary central nervous system (CNS) melanoma is a rare entity. Primary CNS malignant melanomas account for 1 % of melanomas and 0.07 % of intracranial tumours. These are highly aggressive and are ...associated with poor prognosis. Herein, we have discussed one such rare case of PIMM.
62-year-old man with primary CNS melanoma underwent craniotomy and resection of left temporal lesion. Postoperative MRI showed no evidence of residual disease. He received 28 fractions of radiation. Follow-up MRI showed no evidence of disease. However, he later developed worsening symptoms and repeat imaging revealed disease progression with hydrocephalus and drop metastasis to spine. He underwent VP shunting and was started on Temozolomide. He progressively declined functionally and eventually died from his disease.
Primary CNS melanoma is characterized by its rarity, challenging diagnosis, and aggressive behaviour. Current literature suggests limited treatment options, which depend on complete resection of the primary tumour. Molecular analysis may play a key role in deciding future treatment options, including immune checkpoint inhibitors and targeted therapies targeting the BRAFV600E mutation.
Primary intracranial malignant melanoma (PIMM) is an extremely rare tumour of CNS, and its treatment paradigm is very limited based on available literature. Currently any long-term survival depends on the complete resection of tumour. Our case is unique as it talks about the limited therapeutic options in case of rapidly declining performance status in a resource constraint setting.
•This case report presents a rare primary intracranial malignant melanoma (PIMM) with limited therapeutic options due to rapid performance decline and resource constraints.•Difficulty establishing diagnosis and obtaining molecular testing due to poor functional status and financial limitations.•Temozolomide chosen based on existing research despite lack of molecular profiling, considering resource limitations and rapid decline.•Emphasizes the emotional and financial burdens of a rare diagnosis and limited treatment options in a resource-poor setting.
