Proliferating trichilemmal tumor (PTT) is an uncommon adnexal neoplasm that probably arises from a preexist-ing trichilemmal cyst subsequent to trauma or inflammation it can also occur without a preexisting cyst. There is a histological debate regarding the definition of malignant and benign lesions. Being a rare dermal tumor, in order to minimise the metastatic spread of the proliferating trichilemmal tumor after the diagnosis and initial treatment, an appropri-ate strategy should be developed "Proliferating trichilemmal tumors: CT and MR imaging findings in two cases, one with malignant transformation".Pilar cysts (trichilemmal cyst, tricholemmal cyst, wen).

Beneath the epidermis, multiple lobulated expansile masses of squamous cells with non-lamellated trichilemmal keratinization and patchy calcification are seen throughout the dermis and subcutis. INTRODUCTION: Proliferating Trichilemmal Tumors (PTT), are rare benign neoplasm with potential for malignant transformation, commonly affecting the scalp with high recurrenceThis represents the importance of the knowledge and modality of treatment of such a case with the unique presentation.

The appropriate treatment includes wide resection and dose postoperative follow-up of the patient to facilitate the early diagnosis of distant metastases. To report a case of a malignant proliferating trichilemmal tumor (PTT) in the right postauricular region, and to describe the clinical and histopathologic findings.An extend excision is the main treatment after diagnosis. Malignant Proliferating Trichilemmal Tumor. In essence, therefore, the rare MPTT occurs in middle aged and older women, has no racialTreatment of both benign and malignant tumors is by wide excision, and in the latter, a one centimeter margin of normal tissue around the mass must be excised. The even rarer malignant proliferating trichilemmal cyst has been reported in about 30 patients until now.
A case of such a malignant tumour occurring on the ear of a 79 year-old male is presented. The clinical presentation, histological appearance, treatment and differential diagnosis is presented and Proliferating Trichilemmal Tumor (PTT) is a very rare usually benign tumor found in the scalp and face of elderly females.Group II PTTs are low-grade malignant tumors. Local recurrence may be observed in these lesions. Reported here is the first case of a malignant proliferating trichilemmal tumor treated with radical radiotherapy.These tumors have a tendency to develop in older patients, and have a propensity for affecting women more than men. The standard of treatment is surgical excision with a margin of 14. Hayashi I, Harada T, Muraoka M, Ishii M.

Learn in-depth information on Malignant Proliferating Trichilemmal Tumor (MPTT), its causes, symptoms, diagnosis, complications, treatment, prevention, and prognosis.It is also known as a Malignant Proliferating Trichilemmal Tumor/Cyst. However, distant metastasis of proliferating trichilemmal tumors has been rarely reported in the literature. Here, we present a case of malignant proliferating trichilemmal tumor of the scalp with a metastasis to pleura.

This case exemplifies the dif-ficulties in diagnosis and treatment of these rare tumors and their unpredictable course. In this report, we describe a patient who sought treatment at our clinic for a right occiput scalp nodule measuring 1 cm in diameter.Excisional biopsy of the mass was performed and the pathologic diagnosis returned as malignant, proliferating trichilemmal (pilar) tumor.

Mild cytologic atypia and increased mitotic activity can be seen, making differentiation from malignant proliferating trichilemmal tumor or squamous cell carcinoma sometimes difficult. Infiltrative growth, marked atypia, high mitotic activity The potential for PTT to undergo transformation to a Malignant Proliferating Trichilemmal Tumor (MPTT) is unknown, with only about 40 cases of MPTT having ever been reported.In this case report we discuss the diagnosis, histo-pathological characteristics, and surgical treatment of such tumors.

The tumor shows abrupt keratinization of malignant proliferating trichilemmal tumor (MPTT)MPTT can occur de novo but most often arises The efficacy of alternative treatments for malignant cases in a preexisting benign proliferating trichilemmal cyst, cannot be safely evaluated in view of Proliferating trichilemmal tumor (proliferating tricholemmal tumor, proliferating pilar cyst ICD-9 706.2).Mild cytologic atypia and increased mitotic activity can be seen, making differentiation from malignant proliferating trichilemmal tumor or squamous cell carcinoma sometimes difficult. Abstract. Proliferating trichilemmal tumor (PTT) is a benign tumor originating from the outer root sheath of a hair follicle. Malignant transformation in case of PTT is very rare and unusual finding. The therapeutic approach in malignant proliferating trichilemmal tumor consists of wide local excision with a 1cm margin of normal tissue and long-term follow-up. The patient should be followed closely after surgery. The efficacy of alternative treatments for malignant cases cannot be safely We report a case of malignant proliferating trichilemmal tumor showing multiple distant metastases. The patient demonstrated a round mass in the right occipital area for 12 months and the lesion grew rapidly to assume 86.54cm in diameter Histopathological examination of the mass revealed a malignant proliferating trichilemmal tumour. During follow-up 4 months later, a palpable small upper jugular lymph node was noted at the left side of the neck. Malignant proliferating trichilemmal tumor Fig. 1. Polygonal cells reminiscent of outer root sheath without ker- atohyaline granules characterize this entitySummary of reported cases of a spindle cell component arising in trichilemmal tumors Group Patient Site Duration Immuno Treatment Outcome We reported a low-grade malignant proliferating trichilemmal tumor in this patient and detected no relapse or metastasis in a 24-month period of follow-up.An accurate differential diagnosis is crucial because it will affect the treatment approach for the patient. In this report, we describe a patient who sought treatment at our clinic for a right occiput scalp nodule measuring 1 cm in diameter.Excisional biopsy of the mass was performed and the pathologic diagnosis returned as malignant, proliferating trichilemmal (pilar) tumor. Key words: Malignant proliferating trichilemmal tumor, Breast Proliferating trichilemmal tumor is a rare neo- plasm derived from the outer root sheath of the hair follicle.Because the tumor was very fragile and easy to extract, in- cisional biopsy was performed to decide the course of treatment.

Proliferating trichilemmal cysts (also known as a "Pilar tumor", " Proliferating follicular cystic neoplasm", "Proliferating pilar tumor", and " Proliferating trichilemmal tumor") are a cutaneous condition characterized by proliferations of squamous cells forming scroll-like structures.:678.
