Symptoma

Trichofolliculoma

Mostly, it presents as a papule or nodule, involving the skin of the face and scalp area. A central, dilated keratin plugged ostium with vellus hair(s) is often present. [ncbi.nlm.nih.gov]

Sebaceous glands may or may not be present. Lymphocytic or granulomatous inflammation may be present in the connective tissue stroma. [histopathology-india.net]

  • Asymptomatic

    It presented as an asymptomatic, 10 mm deep sinus and histology showed keratin-filled cysts or sinuses lined by stratified squamous epithelium. [ncbi.nlm.nih.gov]

    Trichofolliculomas generally are asymptomatic and are not associated with any systemic or other cutaneous diseases. Therefore, no treatment is required. [thefreelibrary.com]

    The lesion was otherwise asymptomatic and had not previously been treated. The provisional clinical diagnosis was either a keratoacanthoma or a molluscum contagiosum. [journals.lww.com]

  • Otalgia

    We present a case of a 7-year old girl who presented with bloody otorrhea, aural fullness, and otalgia, in the irst pediatric report of trichofolliculoma of the external auditory canal. [semanticscholar.org]

  • Normal Hair

    In spite of the well known regressive changes of normal hair follicles during catagen and telogen, the possibility of corresponding changes in the trichofolliculoma has not yet been discussed in the literature. [ncbi.nlm.nih.gov]

  • Suggestibility

    In the TF lesions, no features indicating the replacement of the regressing secondary hair follicles by any sebaceous elements were observed, thereby suggesting that FSCH is not a very-late-stage TF. 2017 Japanese Dermatological Association. [ncbi.nlm.nih.gov]

    The finding of cohesive, branching keratinized squamous cell clusters admixed with sebaceous cells may suggest a diagnosis of trichofolliculoma, as was seen in the present case. [mayoclinic.pure.elsevier.com]

    Findings in NLCS are reminiscent of fetal adipogenesis; pinocytosis and condensation of the plasma membrane and the many vascular elements in contact with adipocytes suggest a vascular origin of the adipose cells. [e-ijd.org]

What is the treatment of trichofolliculoma? Trichofolliculoma is a benign follicular tumour that requires no treatment. Occasionally they may be excised for cosmetic reasons or if they occur in functionally sensitive areas. [dermnetnz.org]

While the etiology is largely known, it is considered to be a hamartoma with follicular differentiation that results when the pluripotent skin cells cease to differentiate into the hair follicle. [thefreelibrary.com]

An incomplete removal may result in its recurrence Cauterization (burning-off) of the nodule can be performed using a CO2 laser How can Trichofolliculoma be Prevented? Currently, there are no known methods to prevent Trichofolliculoma occurrence. [dovemed.com]

If laser treatment is attempted with deeper and multiple passes, recurrence can be prevented, but there is an increased risk of scarring. Electrosurgery can also be used, but hypopigmented scars may replace the lesions because of thermal effects. [dermatologyadvisor.com]
