Basal-cell carcinoma with matrical differentiation (BCC-MD) is one of the rarest pathologic variants of basal-cell carcinoma, of which 41 cases have been so far reported in detail. One of them developed in a heart-transplant recipient. We report a new case of BCC-MD occurring in a renal-transplant recipient and review the relevant literature. A 75-year-old white man who had received a renal allograft 7 years ago developed a tumor on the left temple clinically suggestive of basal-cell carcinoma. Microscopically, the tumor associated features typical of basal-cell carcinoma (basaloid lobules with peripheral palisading and clefting) and pilomatricoma (presence of shadow/ghost cells)...

Pilomatrix (pilomatrical) carcinoma is a rare cutaneous adnexal tumor with matrical differentiation and recurrent and metastatic potential. Sarcomatoid pilomatrix carcinoma is a rare variant which shows a sarcomatoid component intermingling with the epithelial one. There are only 4 cases previously published. We present an additional case on the hand of a 78 year-old man which appeared as a 6 mm hyperkeratotic, focally ulcerated plaque. A shave biopsy demonstrated a dermal infiltrative neoplasm, composed of markedly atypical-appearing basaloid cells with focal necrotic/ghost cells, as well as an intimately associated population of atypical oval to spindle-shaped cells...

Pilomatrix carcinoma is an exceedingly rare skin adnexal neoplasm derived from piliferous follicles, usually occurring in the head and neck region. Localization of this tumor in the breast is a rarity. We now report an unusual case of a 49-year-old female who presented with a palpable mass in the left breast for 2 years. Mammogram revealed a large, lobulated opacity with calcification, and positron emission tomography-computed tomography showed a metabolically active soft tissue mass measuring 15 cm involving all the quadrants of the left breast...

Pilomatrix carcinoma is a rare, locally aggressive tumor with a tendency to recur. Distant metastases have been reported, with pulmonary lesions being the most frequent manifestation. Similar to pilomatrixoma, pilomatrix carcinoma typically presents as a nontender, firm dermal swelling and is found most commonly in the head and neck region. Although pilomatrixomas and pilomatrix carcinoma are well-recognized lesions, clinically they are frequently misdiagnosed as other skin conditions. By reviewing the literature over the past 10 years, the aims of this review are to analyze the cause, clinical presentation, histopathologic features, management and outcomes of pilomatrix carcinoma amongst children and adults...

This case report describes an unusually large facial pilomatrix carcinoma (PC) in a 60-year-old man. This PC had been growing slowly for 11 months and had recently ulcerated. It measured 9 cm × 7 cm × 5 cm. Initial punch biopsy findings were inconclusive. The tumor was excised in total with 5-mm margins in a supra-superficial musculoaponeurotic system plane. The defect was reconstructed with a cervicofacial bilobed rotational advancement flap. Histopathologic findings confirmed the diagnosis of PC...

Pilomatrix carcinoma is a very rare malignancy, with ~130 cases reported in the literature. In the past, pilomatrix carcinoma was considered to be a low-grade malignant tumor. Currently, however, its significant recurrence and metastatic potential has been well documented. Lymph node and systemic metastases are frequently observed. Wide surgical excision of the primary lesion is the principal modality of treatment, whereas adjuvant radiotherapy may be beneficial in local tumor control. Lymph node metastases may be treated surgically or with radiotherapy...

Pilomatrix carcinoma is a rare cutaneous tumor derived from follicular matrix cells. It may arise de novo or from a malignant transformation of a pilomatrixoma. The latter process has been associated with impaired immune system surveillance of the host caused by UV radiation or the onset of an underlying malignant neoplasm. We report a case of a 58-year-old man presenting with a long-standing pilomatrix carcinoma on the inner right leg after 10 years of repeated curettage of the lesion, concurrent with a high-grade B-cell lymphoma on the same extremity...

A 76-year-old Caucasian man presented to the dermatology clinic for evaluation of a growing lesion in his right preauricular area. He first noticed the lesion several months prior to presentation but felt it had enlarged significantly in the past month. He denied any pain, pruritus, or bleeding. His medical history was significant for melanoma of the nose treated 47 years ago, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and chronic back pain. The patient reported having the melanoma treated but was unaware of any other details concerning the lesion...

We describe the FDG PET/CT findings in an exceedingly rare case of metastatic pilomatrix carcinoma (PC). A 76-year-old man, who underwent incisional biopsy of a soft-tissue mass in the frontal scalp that revealed PC, was referred for an F-FDG PET/CT scan for staging purposes. PET/CT showed areas of increased radiotracer uptake corresponding to frontal mass and unsuspected lung lesions, which were later confirmed as metastases from PC at histological analysis. Clinical condition deteriorated rapidly, and the patient died 3 months after the initial diagnosis...

Malignant pilomatrixoma or pilomatrix carcinoma is a rare, locally aggressive malignant neoplasm, derived from the hair follicle with a high propensity for local recurrence. Only a few cases of metastatic pilomatrixoma have been described in the literature. Till date, only 17 cases have been reported in the English-language medical literature, most commonly occurring associated with local recurrence in adults. We report the first case in children of a metastatic malignant pilomatrixoma in an 8-year-old girl presenting with a recurrent pilomatrix carcinoma of the forehead with metastases in cervical and parotid lymph nodes...

Diagnosis of midline neck swellings may give a myriad of options, ranging from ranula, thyroglossal duct cyst, cystic hygroma, cystic lymphangioma, epidermoid, dermoid and teratoid cysts to benign or malignant neoplasms of the mucosa or salivary glands and also rare skin appendage tumours like pilomatricoma or pilomatrix carcinoma. Various pitfalls are encountered in diagnosing these midline swellings as most of the features are overlapping. Careful history and examination have to be complemented with other diagnostic aids such as conventional radiography, ultrasonography, aspiration cytology and computed tomography to arrive at a correct diagnosis...

Pilomatrixoma is a slowly growing benign tumor of the dermal hair cells. Metastatic disease is exceptionally rare. Pilomatrixoma can occur at any age, but most patients are older than 40 years at presentation. Approximately 60% of these lesions occur in the head and neck region. Their size is usually about 4 cm at the time of presentation. Surgical excision with adequate margins is still the preferred treatment. We report a case of an aggressive malignant metastatic pilomatrixoma in a 43-year-old woman who underwent multiple extensive local resections...

Matrical carcinoma (pilomatrix carcinoma) is a rare follicular low-grade malignancy with matrical differentiation. A pigmented variant with admixed dendritic melanocytes is exceedingly rare with only 7 cases reported in the literature. The diagnosis of malignancy can be difficult to establish. The authors report a case of a 79-year-old woman with a matrical carcinoma who presented with an ulcerated nodule on the posterior right leg, measuring 2.2 cm in greatest dimension. The excisional biopsy showed irregularly shaped dermal and subcutaneous nodules ranging in size from 0...

Pilomatrix carcinoma (PC) is a rare neoplasm, particularly in the parotid region. Thus, it is easily misdiagnosed and an optimal treatment regimen has not yet been established. The present study reports the case of a 43-year-old female who presented with a PC of the parotid region and reviews the associated published literature. The patient underwent three surgical excisions prior to the tumor being completely removed, and was misdiagnosed four times prior to the correct diagnosis. Once the tumor was completely removed, the patient received radiation therapy (RT)...
