Epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKIs)are used as first-line treatment for patients with EGFR-mutated non-small cell lung cancer(NSCLC). Afatinib, a second-generation EGFR-TKI, is also effective against central nervous system(CNS)metastasis of NSCLC. However, patients treated with EGFR-TKI for many months may be at an increased risk of CNS metastasis due to the development of resistance in tumor cells to EGFR-TKI. The average period for development of resistance to EGFR-TKI is 8 to 10 months after the initiation of treatment...

Epidermal inclusion cysts (EICs) are the most common cutaneous cysts, occurring anywhere in the body but infrequently on the breast. It is usually seen in the third and fourth decades of life and very rarely seen in children. They can be either congenital or posttraumatic. Most of the EICs described in children were secondary to trauma. Congenital EIC on the breast is quite a rare entity. Thus, we herein describe two cases of congenital EIC on the breast in two infants of 3 months and 9 months of age, which to the best of our knowledge has not been reported previously...

Introduction: Granular cell tumors (GCTs) are of neuroectodermal origin and account for 0.5% of soft tissue tumors. They are most prevalent in African-Americans in the fourth to sixth decades, with a predilection for the head and neck regions. GCTs usually resemble more common lesions and hence are difficult to diagnose preoperatively. The tumor is readily identified on needle biopsy. Although usually benign with a malignancy rate of only 2-3%, the malignant form has a reported 3-yr mortality of 60%...

BACKGROUND: Umbilical lesions are rare, and can be benign or malignant. This retrospective study was conducted to assess the epidemiological, clinical, and histologic characteristics of umbilical masses. METHODS: Cases of umbilical masses from January 1994 to August 2016 were retrieved from our institution's pathology databases, and their clinicopathological features were reviewed. RESULTS: There were a total of 99 cases of umbilical masses, 78 women (78...

Epidermoid cysts are common benign lesions of hair-bearing, and less often glabrous skin. They can also occur in oral mucosa and internal organs. In case of cutaneous lesions, an epidermal punctum is a clinical diagnostic hallmark. The clinical presentation is variable leading to some differential diagnoses. Diagnosis of epidermoid cysts needs histopathological confirmation - not only of the potential of malignant transformation. The treatment of choice is surgery. We report a retrospective analysis of 2159 epidermoid cysts treated surgically...

PURPOSE: Benign masses of the eyebrow and forehead are common in pediatric patients and can result in facial asymmetry, discomfort, or super-infection. Excision is classically conducted via an incision directly over the mass, which can produce sub-optimal cosmesis. Recently, an endoscopic approach using pediatric brow-lift equipment has been adopted. We reviewed our center's experience with endoscopic removal of benign facial lesions and compared these cases with an equivalent series of open cases...

Dermoid cyst is an example of choristoma (i.e., tumors that originate from aberrant primordial tissue which result in normal appearing tissue in an abnormal location). This particular type of cyst is formed at the site where 2 suture lines of the skull close during embryonic development, and during this time, dermal or epidermal elements are pinched off which later convert to form cysts. Approximately, 50% of these tumors that involve the head are found in or adjacent to the orbit. This article presents a similar case of the orbital dermoid cyst with its management and also a review on other varieties of dermoid cysts of the head and neck region...

Skin lesions are often submitted to oral and maxillofacial pathology practices. The purpose of this study is to evaluate the frequency, distribution, variability, and composition of dermatologic lesions within a large oral and maxillofacial pathology biopsy service. An IRB-approved retrospective search of skin lesions diagnosed at University of Florida oral and maxillofacial pathology biopsy service between 1994 and 2015 was performed. 2487 cases were included in the study. Gender was reported in 2466 cases, of which 59% were male and 41% female...

Objective: The purpose of this study is to present mammography and ultrasound findings of male breast lesions and to investigate the ability of diagnostic modalities in estimating the evolution of gynecomastia. Materials and Methods: Sixty-nine male patients who admitted to Taksim and Bakirkoy Education and Research Hospitals and underwent mammography (MG) and ultrasonography (US) imaging were retrospectively evaluated. Duration of symptoms and mammographic types of gynecomastia according to Appelbaum's classifications were evaluated, besides the sonographic findings in mammographic types of gynecomastia...

Giant congenital melanocytic nevi may be symptomatically isolated or syndromic. Associations with capillary malformations are exceptional, and development of epidermal cysts has not been described. A 71-year-old patient with a giant congenital melanocytic nevus (CMN) of the lower back, buttocks, and thighs was asymptomatic except for unexpected hemorrhage during partial surgical excision years before. Blunt trauma at age 64 initiated recurrent, severe pain under the nevus; multiple large epidermal cysts then developed within it...

Background: Epididymal lesions are uncommon in clinical practice. Few case series has been described in the literature documenting the role of cytology in the evaluation of epididymal nodules. This study was undertaken to analyze the cytomorphology of epididymal nodules and to evaluate role of fine-needle aspiration biopsy (FNAB) in early definitive diagnosis of epididymal nodules. Materials and Methods: A total of seventy cases of epididymal nodules were aspirated over a period of 6 years in the Department of Pathology...

Glomus tumor in the genital area is extremely rare, with an extensive search in the medical literature revealing only 1 case arising in the scrotum. They can be easily mistaken, both clinically and radiologically, for skin neoplasms or primary testicular tumors involving the scrotum. This report presents a case of a 54-year-old man who presented with a painful right scrotal swelling. Ultrasound suggested the possibility of an epidermal inclusion cyst. The excised mass was diagnosed as a benign glomus tumor...

Dissecting cellulitis of the scalp (DC) is a chronic inflammatory condition of the scalp that ultimately leads to scarring alopecia. A healthy 19-year-old male presented with a solitary, soft, alopecic nodule that had appeared 1 year before. A color Doppler ultrasound examination showed a hypodermal anechoic fluid collection in the left parietotemporal region of the scalp, connected to the base of widened hair follicles, and presented inner echoes suggestive of debris, as well as several fragments of hair tracts...

Epidermal cyst is a dermal or subcutaneous epithelial cyst that contains keratin and is lined by true epidermis. Although extremely rare, it can cause pathology including nerve compression syndrome. We report a rare case of ulnar nerve compression in the elbow that was caused by olecranon bursitis and concomitant epidermal cyst in a 67-year-old man. The ulnar nerve was immediately adjacent to the olecranon bursa and was significantly compressed. There was no connection between the tumor and the ulnar nerve...

Sarcoidosis is a systemic inflammatory disease characterized by non-caseating granulomas of unknown origin. Of the fewer than 6% of sarcoidosis cases that occur in subcutaneous tissue, most occur on the face or forearm, but rarely in the toe. A 33-year-old man was admitted to our institute with a 2-cm mass on his chin and a 0.5-cm mass on his right fourth toe. Based on preoperative ultrasonography, epidermal cysts were suspected, and histopathological tests were performed after removing the masses. Histopathologically, the chin and toe tissue samples showed chronic granulomatous inflammation, without necrosis, indicative of sarcoidosis...

BACKGROUND: Dysregulated DNA repair and cell proliferation controls are essential driving forces in mammary tumorigenesis. BCCIP was originally identified as a BRCA2 and CDKN1A interacting protein that has been implicated in maintenance of genomic stability, cell cycle regulation, and microtubule dynamics. The aims of this study were to determine whether BCCIP deficiency contributes to mammary tumorigenesis, especially for a subset of breast cancers with 53BP1 abnormality, and to reveal the mechanistic implications of BCCIP in breast cancer interventions...
