What is Infundibulocystic basal cell carcinoma?

What is Infundibulocystic basal cell carcinoma?

Infundibulocystic basal cell carcinoma is a rare subtype of the most frequent form of human skin cancer (basal cell carcinoma). It was first described in 1987 and proposed as a new basal cell carcinoma (BCC) variant by Ackerman and Walsh in 1990 [1,2].

What is Basaloid follicular hamartoma?

Introduction: Basaloid follicular hamartoma (BFH) is a rare, benign neoplasm of the hair follicle, characterized by multiple brown papules involving the face, scalp, and trunk. It is described by multiple clinical forms, and can present as localized or generalized.

What is Basaloid proliferation?

Background: Basaloid epidermal proliferations, which histologically resemble basal cell carcinoma, have been described overlying dermatofibromas. Several etiologies have been proposed. Cutaneous myxomas are also benign mesynchymal tumors. Purpose: Basaloid proliferations have been noted overlying cutaneous myxomas.

Is basal cell tumor benign or malignant?

Basal cell carcinoma (BCC) is most often a benign form of skin cancer caused by exposure to ultraviolet (UV) light. However, it’s the most frequently occurring form of all skin cancers, with more than 3 million people developing BCC in the U.S. every year. 1.

What does Infundibulocystic mean?

A rare type of basal cell carcinoma that usually arises on the face, which resembles keratotic type BCC.

What does Basaloid mean?

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of oral squamous cell carcinoma with a predilection for the tongue and in other locations, such as floor of the mouth, palate, retromolar trigone, and gingival mucosa.

What is a Basaloid tumor?

Basaloid tumours are defined as those that appear more blue than pink on haematoxylin and eosin (H&E) staining. Basophilia is a consequence of a high nuclear:cytoplasmic ratio and relatively con- densed nuclear chromatin. Basal cell carcinoma (BCC) is the prototypical basaloid skin tumour.

What is Infundibular epithelium?

The infundibulum is the funnel-shaped, uppermost epithelial segment of the hair follicle.

How long can you live with basal cell carcinoma?

The 5-year relative survival for BCC is 100%. This means that, on average, all of the people diagnosed with BCC are just as likely to live at least 5 years after their diagnosis as people in the general population. The 5-year relative survival for SCC is slightly less at 95%.

Are lung hamartomas common?

Pulmonary hamartomas (alternative plural: hamartomata) are benign neoplasms composed of cartilage, connective tissue, muscle, fat, and bone. It is one of the most common benign tumors of the lung and accounts for ~8% of all lung neoplasms and 6% of solitary pulmonary nodules.

How big can lung hamartomas get?

The prognosis is excellent. Pulmonary hamartomas grow slowly, and most of them are smaller than 4 cm, although they may reach 10 cm in diameter. The tumors are usually solitary, although multiple tumors in the Carney triad have been reported.
