Prominent entrapment of respiratory epithelium in primary and metastatic intrapulmonary non-epithelial neoplasms: a frequent morphological pattern closely mimicking adenofibroma and other biphasic pulmonary lesions.

Virchows Arch 2020 Aug 19;477(2):195-205. Epub 2020 Mar 19.

Institute of Pathology, Friedrich-Alexander University Erlangen-Nürnberg (FAU), University Hospital, Krankenhausstrasse 8-10, 91054, Erlangen, Germany.

As one of the most common target organs for hematogenous spread from diverse cancers, biopsy interpretation of lung tumors is complicated by the challenging question of primary versus metastatic and by frequent entrapment of native respiratory glands. Nevertheless, the literature dealing with this issue is surprisingly sparse and no single study has been devoted to this topic. We reviewed 47 surgical lung specimens of non-epithelial neoplasms (38 metastases, mainly from sarcomas and 9 primary lesions) for frequency and pattern of intralesional epithelial entrapment.

Department of General Surgery, Fr. Muller Medical College Hospital, Kankanady, Mangalore, Karnataka 575002 India.

Chest wall hemangiomas are rare tumors that may originate within the soft tissue or from the ribs. Intramuscular hemangioma is infrequent, representing less than 1 % of all hemangiomas, and the localization in the chest wall is even less frequent. They are typically cutaneous in location, large, and poorly circumscribed and can be locally destructive. Read More

Fibroadenoma in Axillary Ectopic Breast Tissue Mimicking Lymphadenopathy.

J Clin Diagn Res 2017 Mar 1;11(3):ED01-ED02. Epub 2017 Mar 1.

Professor, Department of Pathology, Mahatma Gandhi Mission's Medical College, Navi Mumbai, Maharashtra, India.

Swellings in the axilla especially in women are always viewed with suspicion owing to a large number of these being associated with breast carcinoma presenting as nodal metastasis. In a country like India, tuberculous lymphadenopathy is also amongst the first differentials. We present a case of a woman with right sided axillary swelling mimicking lymphadenopathy which on Fine Needle Aspiration Cytology (FNAC) turned out to be fibroadenoma of the ectopic breast tissue.

Spatial Compounding Technique to Obtain Rotation Elastogram: A Feasibility Study.

Ultrasound Med Biol 2017 06 19;43(6):1290-1301. Epub 2017 Apr 19.

Department of Applied Mechanics (Biomedical Engineering Group), Indian Institute of Technology, Madras, Chennai, India. Electronic address:

The perception of stiffness and slipperiness of a breast mass on palpation is used by physicians to assess the level of suspicion of a lesion as being malignant or benign. However, most current ultrasound elastography imaging methods provide only stiffness-related information. There is no existing approach that provides information about the local rigid body rotation undergone by only a loosely bonded, asymmetrically oriented lesion subjected to a small quasi-static compression.

Tumor characterization and treatment monitoring of postsurgical human breast specimens using harmonic motion imaging (HMI).

Breast Cancer Res 2016 05 9;18(1):46. Epub 2016 May 9.

Department of Biomedical Engineering, Columbia University, 351 Engineering Terrace, 1210 Amsterdam Avenue, New York, NY, USA.

Background: High-intensity focused ultrasound (HIFU) is a noninvasive technique used in the treatment of early-stage breast cancer and benign tumors. To facilitate its translation to the clinic, there is a need for a simple, cost-effective device that can reliably monitor HIFU treatment. We have developed harmonic motion imaging (HMI), which can be used seamlessly in conjunction with HIFU for tumor ablation monitoring, namely harmonic motion imaging for focused ultrasound (HMIFU).

Five-Year Disease-Free Follow-Up of a Borderline Breast Phyllodes Tumor in a 15-year-old Patient.

J Breast Health 2015 Jul 1;11(3):138-140. Epub 2015 Jul 1.

Department of General Surgery, Marmara University Faculty of Medicine, İstanbul, Turkey.

Phyllodes tumors are large breast tumors representing only 1% of breast neoplasms and are rarely seen in young women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant based on the characteristics of the stroma. Although wide local excision is recommended for the treatment modality, the reoccurrence rate after surgical excision varies between 36% and 65%, with recurrence more likely in those with the tumor at the margins of excision.

Neglected giant fibroadenoma of the breast presenting like a fungating breast cancer in a premenarchal Nigerian teenager.

West Afr J Med 2012 Jul-Sep;31(3):211-3

Department of Surgery, College of Health Sciences, Obafemi Awolowo University, Ile Ife , 220005 Osun State.

Background: Giant fibroadenoma of the breast is a type of rare benign breast tumour which can grow to a giant size, It is even rarer for this benign tumour to grow rapidly, ulcerate spontaneously and present like a fungating breast tumour in a way mimicking breast cancer. Carcinoma of the breast on the other hand has been on the increase so much that it has assumed an epidemiological dimension. In developing country such as Nigeria late presentation of breast cancer has remained a rule rather than exception and it is very common for patient to present with fungating breast lesion.

Fine-needle aspiration of gray zone lesions of the breast: fibroadenoma versus ductal carcinoma.

Diagn Cytopathol 2013 Sep 31;41(9):806-11. Epub 2012 Aug 31.

Department of Pathology, University of Michigan, Ann Arbor, Michigan.

While breast lesions have characteristic cytological features, some lesions, particularly adenocarcinoma and fibroadenoma, may present with overlapping features causing erroneous diagnoses. The current study aimed to define significant cytomorphologic features predictive of fibroadenoma and adenocarcinoma, respectively. Further, we intended to evaluate the predictive characteristics for differentiation between gray zone lesions and to identify root causes contributing to misdiagnoses. Read More
