Background : Pilomatrixoma , also known as Malherbes’s calcifying epithelioma, known to occur in children, is not common especially in middle aged and those below 10 years of age . Pilomatrixoma presents as a firm skin nodule on eye lid or eye brow, so should be considered in the differential diagnosis of such lesions involving eyelids. Case : A 45-year-old male presented with a swelling in the...

Pilomatrixoma is a rare, benign, calcifying cutaneous tumor, originating from pluripotential precursors of hair matrix cells. It is most commonly seen in the head and neck region, occurring in the first two decades of life. It usually occurs as a single nodule with a diameter of 0.5-3 cm, localized dermally or subcutaneously. Clinical diagnosis may be difficult when it presents in a large, ulce...

Malherbe’s calcifying epithelioma is an uncommon cutaneous tumour that originates from the matrix cells of hair follicle. It was initially described by Malherbe as a benign calcifying epithelioma. Several ultra-structural and electron-microscopic studies later demonstrated its origin from matrix cells and the term pilomatrixoma was introduced. The treatment of this tumour remains mainly surgica...

The aim is to present a case of pilomatrixoma in the periocular area in a 10-year-old female through retrospective review of medical records of a single patient. A 10-year-old female developed a lesion under her right eyebrow over a period of one year. The rest of the ophthalmic history was unremarkable. On examination, oval, well-defined, subcutaneous tumor measuring 7 x 4 mm was found under t...

Two cases of adult testicular teratoma with shadow cell differentiation (SCD) similar to that seen commonly in pilomatrixoma are presented. The patients aged 21 and 27 years, and both tumors were limited to the testis. The differentiation of squamous epithelium toward shadow cells is well known in cutaneous pilomatrixoma and related lesions, some odontogenic tumors, craniopharyngeoma, and it wa...

Introduction: Pilomatrixomas are benign neoplasms derived from hair follicle matrix cells. They among the most common soft tissue head and neck tumors of childhood. typically isolated, slow-growing, firm, nontender masses that adherent to epidermis but mobile in subcutaneous plane. This clinical presentation is so characteristic many experienced surgeons will excise suspected pilomatrixomas wit...
