What is a 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.
What is Basaloid epithelial neoplasm?
The basaloid squamous cell carcinoma (BSCC) is a variant of squamous cell carcinoma, having histologically distinctive features and appearing in the oral cavity, upper respiratory tract and esophagus. Histological hallmarks are the presence of a basaloid component in intimate association with squamous cell carcinoma.
What is Fibroadnexal dysplasia?
“Fibroadnexal hamartoma (fibroadnexal dysplasia) is a non-neoplastic, benign proliferation of distorted adnexa, fat, and collagen. This process most often forms discrete nodules on the distal extremities of dogs.
Do hamartomas grow?
Hamartomas are noncancerous growths that can appear anywhere on the body. While seen as harmless, these benign tumors can grow to large sizes and cause pressure on surrounding tissues. Depending on where they grow externally or internally, hamartomas can cause life-threatening symptoms.
What are Trichoepitheliomas?
INTRODUCTION. Trichoepithelioma is a rare benign skin lesion that originates from hair follicles. Trichoepitheliomas are mostly seen in the scalp, nose, forehead, and upper lip. These skin lesions originate from benign proliferation of epithelial-mesenchymal origin cells.
What are Basaloid cells?
Basaloid cells are a feature of adenoid cystic carcinoma, but many cells have clear cytoplasm and irregular, angular, hyperchromatic nuclei. A characteristic cribriform pattern is rare and minimal in basal cell adenoma, and infiltration and perineural invasion are definitely not features of basal cell adenoma.
What is a Fibroadnexal hamartoma?
A hamartoma is a nodular disorganized proliferation of various kinds of skin cells. Some involve hair follicles and glands, and these are called fibroadnexal hamartomas. Nodular dermatofibrosis is a syndrome in which multiple nodules form on and in the skin, most commonly on the hind limbs.
What is hamartoma pathology?
A hamartoma (from Greek hamartia, meaning “fault, defect,” and -oma, denoting a tumor or neoplasm) is a benign (noncancerous) tumorlike malformation made up of an abnormal mixture of cells and tissues found in areas of the body where growth occurs.
How do you treat hamartoma?
How are hypothalamic hamartomas treated?
- Resection surgery: A surgeon may perform brain surgery to remove the hamartoma.
- Stereotactic radiofrequency thermoablation: This form of ablation therapy uses heat to treat the hamartoma.
Is there a cure for Trichoepithelioma?
All in all, as a benign tumor, trichoepithelioma can be managed safely with surgical removal. Alternatives include dermal abrasion and laser surgery, curettage although these options may be associated with an increased rate of recurrence.
