“…Although most TCs are benign lesions, there are rare examples of TCs appearing malignancy [13][14][15]. In 2% of trichilemmal cysts, single or proliferating cells lead to tumours called proliferating trichilemmal cysts which may be locally aggressive [13][14][15]. Metastases to regional lymph nodes and distant organs have been rarely observed [13][14][15].…”

A rare ossifying trichilemmal cyst in a young female patient: Case report and literature review

et al. 2022

Trichilemmal cysts constitute the second most common cutaneous cysts and are mostly presented on the scalp of middle aged women. It is, therefore, unusual for a young person to have a trichilemmal cyst and it is extremely rare for a trichilemmal cyst to be ossified. In literature, only 8 cases of trichilemmal cysts with concomitant ossification have been described. We report the case of a 22 year old female who presented with a scalp nodule and was treated via surgical excision of the lesion. The pathology examination of the surgical specimen revealed a lesion consisting of a multilayered squamous epithelium of slightly eosinophilic maturing keratinocytes. There was no granular layer, whereas the core of the lesion was occupied by mature bone tissue with calcium deposits. The definite diagnosis of the pathology report was ossifying trichilemmal cyst. The aim of this report is, to enlighten clinicians about this rare pathological entity.

“…Some believe that the trichilemmal cyst develops as a result of a genetically determined abnormality in the budding of the outer root sheath of hair follicles. The cyst wall's similarity to the sheath at the point of the follicular isthmus lends support to this theory [5].…”

We report a case of pilar cyst in a 50 year old female with a swelling in the left parietal region. Gross findings revealed a cystic cavity with multiple infoldings. The characteristic histopathologic feature of a pilar cyst with absence of granular layer and swollen cells were evident. Attention to detail, prompt diagnosis and treatment based on the signs and symptoms are a must for patient welfare.

“…In addition, hole-body positron emission tomography scanning should be done. However, although metastasis from proliferating trichilemmal tumours is rare, it has been suggested in the literature for a sporadic malignant variant showing an aggressive clinical course with lymph node aggression [14]. Reported have suggested that plastic surgery such as Mohs or excisional surgery is a most effective and tissue-sparing approach for MPTTs [15].…”

Background:Malignant proliferating trichilemmal tumor is a rare skin tumor that affects mainly older women. It similar to differential squamous cell carcinoma. Methods: A search strategy was designed and run in Medline and google scholar. Also, searching grey literature, checking references, tracking citations, hand-searching of focused journals, and websites were utilized for retrieval of related studies. All of articles which studied epidemiology of mortality or injuries of the war were included. Conclusion:Malignant proliferating trichilemmal tumours are rare and cause struggling in diagnosis for the surgeon ‎‎as there is a high risk of recurrence and metastasis‎
