Insights

Vismodegib effectively eradicated an aggressive basal cell carcinoma. This case provides histological evidence of complete tumor clearance, offering hope for difficult-to-treat BCC cases.

Area of Science:

  • Oncology
  • Dermatology
  • Pharmacology

Background:

  • Vismodegib inhibits the Hedgehog signaling pathway.
  • It shows efficacy in advanced basal cell carcinoma (BCC).
  • Complete tumor eradication evidence is limited.

Observation:

  • A 69-year-old male presented with recurrent, infiltrative, and sclerosing (morpheiform) BCC on his upper lip.
  • This BCC subtype is known for its aggressive nature and resistance to conventional therapies.

Findings:

  • A three-month course of vismodegib (150 mg daily) resulted in complete eradication of the BCC.
  • Histological examination confirmed the absence of tumor cells, providing definitive evidence of clearance.
  • Complete histological clearance of aggressive BCC with vismodegib is rarely documented.

Implications:

  • Vismodegib demonstrates potential for complete tumor elimination in aggressive BCC subtypes.
  • This case highlights the importance of histological confirmation for treatment efficacy.
  • Further research into vismodegib for morpheiform BCC is warranted.

Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Ecological Succession02:17

Ecological Succession

Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Laminins are the Adhesive Proteins of Basal Lamina00:55

Laminins are the Adhesive Proteins of Basal Lamina

Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Basal Lamina are the Specialized Form of ECM01:03

Basal Lamina are the Specialized Form of ECM

The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can...
