Adenolipoma of the breast

Adenolipoma of the breast is an uncommon mammary lesion classified as a hamartomatous lesion, presenting as a soft, mobile and well-defined mass. The typical mammographic findings is of a wellcircumscribed lesion containing both fat and soft tissue surrounded by a capsule. Microscopically, adenolipoma exhibits a hamartomatous mixture of ducts and lobules intermingled with adipose and fibroconnective tissue. Enucleation is the standard treatment and recurrences are rare. We report a 29-year-old woman with a mobile, tender and firm mass, 6 x 5 cm, in the upper inner quadrant of the right breast of 1 month duration. Mediolateral mammography images demonstrated a welldefined mass with mixed granular and fat density. Histopathology of the excised mass revealed well-circumscribed lobules of ducts and glandular structures haphazardly embedded in mature fatty tissue. Breast hamartoma should be differentiated from other benign lesions of the breast. Awareness among radiologists and pathologists of this benign lesion would help avoid an incorrect diagnosis and unnecessary intervention.

Different Anatomical Distribution of Basal Cell Carcinoma Subtypes in Iranian Population: Association between Site and Subtype

BACKGROUND: Basal cell carcinoma (BCC) is the most common type of human cancer. Despite the high prevalence of these tumors, there is a lack of reliable epidemiological data in some regions including Iran. OBJECTIVE: To assess the relationship between BCC subtypes and anatomical distribution in the Iranian population. METHODS: There were 876 patients with a single BCC enrolled in this study (March 2007 to March 2010; Razi Dermatology Center, Tehran, Iran). RESULTS: Among 876 patients, 544 were males and 332 females. Of the lesions, 43% were nodular, 32.4% mixed type, 3% superficial and rest of other subtypes. In the lesion location, 58.2% were on the face, 29.2% on scalp, 6.2% on ears, 2.3% on neck, 1.7% on trunk and 1.3% on the extremities. There was no significant difference between male and female in the BCC subtypes, but anatomical distribution of the tumor was different (p=0.002). Most of the trunk-arising BCCs were superficial, and most of the facial BCCs were nodular subtype. Also, most of the BCC subtypes occurred in patients between 40 to 80 years old and mostly on the face and scalp (p=0.04). However, superficial BCCs mostly occurred in younger patients over others (p=0.001). CONCLUSION: Subtype is associated with a site, independent of gender or age. Also BCCs occurring on the trunk are mostly of the superficial subtype.

Cutaneous leiomyoma: novel histologic findings for classification and diagnosis

Smooth muscle tumors rather benign or malignant can arise wherever the muscular tissue presents but cutaneous leiomyoma is one of the rare benign tumors of the which even the diagnostic criteria from the malignant type of the tumor is still in doubt. This study was aimed to compare the subtypes of cutaneous leiomyoma from different histologic aspects in order to find unique criteria for better classification and diagnosis. The six year data base of our center was reviewed and 25 patients with cutaneous leiomyoma were included in this study. Of 25 patients, 5 were female and 20 were male. 5 patients had angioleiomyoma [ALM] and 20 had pilar leiomyoma [PLM]. ALM had following characteristics: dilated vascular canals intermingled with compact smooth muscle bundles; well circumscribe counter and myxoid and hyaline changes through the tumor. In contrast, PLMs had following histologic features: poor defined outline, entrapped hair follicles and eccrine glands, acanthosis and elongated rete ridges with hyperpigmentation and smooth muscle bundles which are interdigitated with elongated rete ridges. Here we introduced some distinct histological features for each subtype of the cutaneous leiomyoma which can lead to create novel criteria for classification and diagnosis of the lesion
