Giant pilomatricoma involving the parotid: Case report and literature review

Preauricular pilomatricoma: An uncommon entity in a dental pediatric patient

“…Although they usually present as slow enlarging, asymptomatic, subcutaneous masses; O’Connor et al [1] reported that nearly%25 could be symptomatic. Surgery consisting of total excision with clear margins is the treatment of choice in order to alleviate possible symptoms and minimize the risk of malignant transformation; recurrence is reported to be rare [2], [5].…”

“…They stated that a false diagnosis of malignancy or of an epidermoid cyst could be made [4]. Mundinger et al [5] reported a case of a large pilomatricoma involving the parotid gland and stated that the lesion should be considered in the differential diagnosis of large check tumors.…”

“…They are most commonly reported in the head and neck region with preauricular region being one of the most frequent locations and have a wide variety of signs, which often causes misdiagnosis [2], [3], [4]. They present as solitary or seldom multiple lesions, which are commonly asymptomatic, superficial, subcutaneous hard masses demonstrating variable degrees of calcification, often attached to the skin but mostly mobile over the underlying tissues; as the tumor grows more superficial, a bluish color or ulceration of the overlying epidermis may be noted [1], [2], [5]. Treatment is by incision and curettage or by excision only [4].…”

Giant pilomatricoma mimicking a malignant parotid mass

“…Unfortunately, the patient failed to return for follow-up after discharge from the hospital. In 2010, Mundinger et al [11] reviewed the adult literature and found that only 5 cases of giant pilomatricoma involving the parotid region had been reported. Notably, all these lesions were initially misdiagnosed as parotid malignancy.…”

“…With regard to giant pilomatricomas involving the parotid region, a variety of reconstructive techniques have been described in the adult literature. Such techniques for coverage of the surgical defect following resection include primary closure, local rotational flap, or split thickness skin graft [11]. We chose to reconstruct the surgical defect with a cervicofacial advancement flap rotated through a pre-and retroauricular facelift incision, which yielded excellent cosmetic result and no postoperative facial nerve deficits.…”
