Tumor Immunotherapy01:27

Tumor Immunotherapy

2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression02:07

Tumor Progression

7.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.9K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Summary

Localized interlobar effusion, a rare finding in congestive heart failure, can mimic a lung tumor. Prompt treatment of heart failure led to the complete resolution of this "phantom tumor," avoiding unnecessary investigations.

Area of Science:

  • Cardiology
  • Pulmonology
  • Radiology

Background:

  • Localized interlobar effusion, also known as a phantom or vanishing tumor of the lung, is an uncommon manifestation of congestive heart failure.
  • This condition can be misdiagnosed as a pulmonary tumor on initial imaging.

Purpose of the Study:

  • To report a case of localized interlobar effusion mimicking a lung tumor in a patient with congestive heart failure.
  • To highlight the importance of considering congestive heart failure in the differential diagnosis of lung masses.

Main Methods:

  • A case report of a 61-year-old male presenting with symptoms suggestive of a pulmonary mass.
  • Diagnostic workup included chest radiography, echocardiography, and electrocardiography.
  • Treatment focused on managing congestive heart failure.

Main Results:

  • Initial chest radiography revealed a nodular mass, leading to suspicion of a pulmonary tumor.
  • Echocardiography identified left ventricular systolic dysfunction and atrial flutter.
  • Following ten days of congestive heart failure treatment, a lateral chest X-ray confirmed pleural effusion with complete regression of the "lung tumor".

Conclusions:

  • Localized interlobar effusion in congestive heart failure can present as a phantom tumor.
  • Early diagnosis and treatment of congestive heart failure are crucial to avoid misdiagnosis and unnecessary invasive procedures.
