A Rare Site of Metachronous Metastases from Renal Cell Carcinoma.

Secondary metastatic involvement of the testis is a rare occurrence, particularly in cases of metastasis from renal cell carcinoma (RCC). We present a case of metachronous contralateral testicular metastasis from RCC in a 55-year-old man, occurring 2 years after radical nephrectomy. Following a thorough evaluation that ruled out systemic disease, the patient underwent a Chevassu procedure and right inguinal orchidectomy.

A Case Report: Mucinous Tubular and Spindle Cell Carcinoma of Kidney with Spindle Cell Predominance Mimicking Mesenchymal Tumour.

Mucinous tubular and spindle cell carcinoma (MTSCC) of kidney is a rare variant of renal cell carcinoma which was first described in the 2004 World Health Organization classification of tumours of the kidney. Morphologically, MTSCC is composed of tubules merging with bland-appearing spindle cells in a myxoid/mucinous stroma. Diverse morphological patterns have been reported in MTSCC; however, a spindle cell predominant morphology mimicking a mesenchymal tumour is rare and only two cases have been reported so far.

Metaplastic carcinoma of the breast: real-world outcome from a tertiary cancer centre in India.

Metaplastic carcinoma (MPC) is a rare subgroup of breast tumours accounting for <5% of all invasive breast cancers. Histologically confirmed 40 MPC from January 2001 to December 2018 were identified from our electronic database: stage I 2.5% ( = 1), stage II 40% ( = 16), stage III 45% ( = 18) and stage IV 12.

LASP-1 interacts with ErbB2 in ovarian cancer cells.

LASP-1 was identified as a protein following mass spectrometric analysis of phosphoproteins consequent to signaling by ErbB2 in SKOV-3 cells. It has been previously identified as an oncogene and is located on chromosomal arm 17q 0.76 Mb centromeric to ErbB2.

SERMs suppresses the growth of ERα positive cervical cancer xenografts through predominant inhibition of extra-nuclear ERα expression.

The role of estrogens and estrogen receptors (ER) in cervical cancer (CC) is not well established. However, epidemiological studies and abundant evidence from genetically engineered mouse models support such hypothesis. In this study, we have addressed estrogen responsiveness in a human CC cell line xenograft mouse model.

The hedgehog pathway regulates cancer stem cells in serous adenocarcinoma of the ovary.

Purpose: Signaling by cancer stem cells (CSCs) is known to occur at least in part through conserved developmental pathways. Here, the role of one of these pathways, i.e.

ALDH1A1+ ovarian cancer stem cells co-expressing surface markers CD24, EPHA1 and CD9 form tumours in vivo.

One of the reasons for recurrence following treatment of high grade serous ovarian carcinoma (HGSOC) is the persistence of residual cancer stem cells (CSCs). There has been variability between laboratories in the identification of CSC markers for HGSOC. We have identified new surface markers (CD24, CD9 and EPHA1) in addition to those previously known (CD44, CD117 and CD133) using a bioinformatics approach.

Expression of cancer stem cell markers CD24, EPHA1 and CD9 and their correlation with clinical outcome in epithelial ovarian tumours.

Background: There has been variability between laboratories in the identification of cancer stem cells (CSCs) markers for epithelial ovarian cancer (EOC). We have evaluated three new surface markers for EOC to identify CSCs precisely.

Methods: Three new putative CSCs specific surface markers CD9, CD24 and EPHA1 identified by a bioinformatics approach were evaluated in normal ovary, fallopian tube and ovarian tumours.

Cancer stem cells contribute to angiogenesis and lymphangiogenesis in serous adenocarcinoma of the ovary.

The origin of blood and lymphatic vessels in high-grade serous adenocarcinoma of ovary (HGSOC) is uncertain. We evaluated the potential of cancer stem cells (CSCs) in HGSOC to contribute to their formation. Using spheroids as an in vitro model for CSCs, we have evaluated their role in primary malignant cells (PMCs) in ascites from previously untreated patients with HGSOC and cell lines.

Multiple adenoid basal cell carcinoma: An uncommon presentation.

Basal cell carcinoma (BCC) is the most common malignant skin tumor which occurs more frequently over the sun exposed parts of body. Its adenoid variant is a rare histological subtype. We report a case of multiple adenoid basal cell carcinomas at unusual sites in a middle-aged male patient.

A facile gold nanoparticle-based ELISA system for detection of osteopontin in saliva: Towards oral cancer diagnostics.

In the current study, we emphasize that osteopontin is overexpressed in oral squamous cell carcinoma. Overexpression of osteopontin levels was confirmed by mRNA quantification studies and immunohistochemistry analysis. Based on this, a gold nanoparticle-based ELISA system was developed for non-invasive osteopontin detection.

Gastric Mucormycosis Masquerading as Gastric Malignancy.

Mucormycosis is an opportunistic fungal infection usually seen in immunocompromised patients. We report a case of gastric mucormycosis in an immune-competent lady that mimicked a gastric malignancy, presenting a diagnostic challenge. A high index of suspicion is required for the diagnosis and successful treatment of this potentially life-threatening condition.

A Rare Case of Multiloculated Cervical Thymic Cyst Masquerading as Tuberculous Adenitis.

Cervical thymic cysts are among the rarest cysts found in the neck. They usually occur during infancy and childhood, and they are extremely rare in adults. They may be found at any level of the pathway of normal thymic descent, from the angle of the mandible to the superior mediastinum.

Repeated dose studies with pure Epigallocatechin-3-gallate demonstrated dose and route dependant hepatotoxicity with associated dyslipidemia.

EGCG (Epigallocatechin-3-gallate) is the major active principle catechin found in green tea. Skepticism regarding the safety of consuming EGCG is gaining attention, despite the fact that it is widely being touted for its potential health benefits, including anti-cancer properties. The lack of scientific data on safe dose levels of pure EGCG is of concern, while EGCG has been commonly studied as a component of GTE (Green tea extract) and not as a single active constituent.

Diagnostic dilemma involving a mass in the parapharyngeal space: A metastatic breast carcinoma masquerading as a malignant salivary gland tumor.

Parapharyngeal space (PPS) tumors are rare and account for about 0.5% of all head and neck neoplasms. Most PPS tumors are benign (up to 80%) while the remaining 20% are malignant.

Primary plasma cell leukaemia with unusual presentations: a case series.

We present here three cases of plasma cell dyscrasias; first case presenting as primary plasma cell leukemia showing unusual morphology and aberrant expression of myeloid markers; the second case presenting as plasma cell leukaemia with atypical plasma cells in peripheral blood and the third case presenting as myelomatous pleural effusion after treatment for myeloma.

Adult acute lymphoblastic leukemia mimicking renal cell carcinoma with wide spread bone metastasis.

A few cases with bilateral renal enlargement in acute lymphoblastic leukemia (ALL) are reported in literature. In this article, we report an unusual case of ALL in an adult presenting as multiple lesions in both kidneys and multiple bone lesions.

Solid pseudo-papillary tumor of pancreas: A rare case report and review of Indian literature.

Solid pseudo-papillary tumor (SPT) of the pancreas is a rare pancreatic tumor, well known for its predilection for young women. As the tumor has favorable prognosis, differentiating it from other pancreatic tumors with aggressive behavior is necessary. We present a rare case of SPT and review the literature about SPT cases published from India.
