Atypical adult non-calcified pilomatricoma

We present a rare case of a non-calcified pilomatricoma in a 67-year-old man. This tumor was extremely large in size, and its location, in the lower extremity, was very unusual. The clinical, radiographic, and histopathological features are described in detail. The role of magnetic resonance imaging (MRI) in the diagnosis of this entity is discussed. Definite internal reticulations and septations were observed. A possible explanation for this observation is that the high signal intensity reticulations may represent edematous stroma surrounding basaloid cells.

Alveolar soft part sarcoma: MR and angiographic findings

Objective. To present the MR and angiographic findings of alveolar soft part sarcoma (ASPS). Design and patients. MR examinations (12 tumors of 10 patients) of ASPS performed at multiple hospitals were retrospectively reviewed. The tumors were found in the thigh (n=4), lower leg (n=4), femur (n=2, local metastasis), scalp (n=1) and arm (n=1). The MR signal characteristics including signal intensity, homogeneity and signal void of lesions and bony invasion including direct invasion or local metastasis were evaluated. Angiographic findings (n=4) and post-embolotherapy follow-up MR imaging (n=2) findings were also assessed. Results. Local bony metastasis was found in two cases. Seven tumors showed heterogeneous high signal intensity on T1- and T2-weighted images with good enhancement. One tumor had a very high signal on T1-weighted images. Eight tumors (67%) showed numerous signal voids in or near the tumors. All four angiographic studies showed numerous enlarged vessels, arteriovenous shunts and delayed washout. Two cases mimicked arteriovenous malformations on angiographic studies but MR images demonstrated solid soft tissue components as well as tortuous vessels. Conclusions. High signal on T1-weighted image and numerous signal voids are highly suggestive of ASPS, although they are not universal as has been suggested and arteriovenous malformation should be included in the differential diagnosis. Local bony metastases in ASPS were seen in two cases and should be carefully investigated.

Maffucci syndrome: Case report and review of diagnostic signs of the rare disease

Maffucci syndrome is a non-hereditary congenital condition that affects the skin and skeleton. Enchondromas (benign cartilage enlargements), bone abnormalities, and venous anomalies (hemangiomas) are all symptoms. Enchondromas occur as a result of mesodermal dysplasia and have the potential to become cancerous. They are most commonly found on the phalanges and long bones. Venous abnormalities commonly manifest themselves as soft lumps or tumors on the distal extremities. A 19-year-old boy presented with swellings on his fingers and left foot since the age of 5, along with a few bluish soft tissue swellings on his left heel. Multiple expansile lytic lesions and soft tissue swellings with phleboliths were seen on X-ray. Histology confirmed the diagnosis of hemangiomas and enchondromas. Soft tissue swellings were found to have hyper echoic areas, as well as modest marginal blood flow on Doppler, which could indicate hemangiomas. Maffucci syndrome was identified, and treatment with a multidisciplinary approach was initiated. Maffucci syndrome is a rare genetic illness reported in the literature less than 200 times. The enchondromas and hemangiomas have a strong link to malignant changes, with chondrosarcomas accounting for 30% of the associated malignancies. On X-ray, enchondromas are easily identified as osteolytic lesions with cortex thinning and endosteal scalloping while color Doppler ultrasound detects the presence of hemangiomas. Phleboliths are easily identified as small calcifications on X-rays. Radiographic examinations should be considered in patients presenting with bone or soft tissue swellings for an early diagnosis of Maffucci syndrome.
