Solitary Supraclavicular Fossa Masses.
OBJECTIVE
The aim of this study is to present the diagnostic spectrum of solitary supraclavicular fossa (SCF) masses in a Turkish context. The demographic data of the patients and the effectivity of the diagnostic tools are also discussed to improve current diagnostic strategies.


METHODS
The charts of patients who underwent surgical intervention for solitary SCF mass of an unknown etiology between January 2005 and January 2015 were reviewed. Patients presenting evidences of synchronous cancers and patients with a history of previous cancers were excluded. The data encompassing the demographics of the patients, the discriminative specifications, the histopathological diagnosis of the masses, and the diagnostic tools used in the workup period were noted. The descriptive data are presented and statistical analyses were performed using the Mann-Whitney test, Fisher exact test, and Chi-squared tests.


RESULTS
In total, 44 male (76%) and 14 (24%) female patients were enrolled in the study. Thirty-five masses (60%) were located in the left SCF and 23 masses (40%) in the right. The masses were categorized as neoplastic (n = 31, 53%), inflammatory (n = 18, 31%), and congenital (n = 9, 16%). The 44 (76%) masses in our series were lymph nodes (LNs), and 25 (57%) of them were malign, whereas 19 (43%) were either inflammatory or benign. Male sex (P = 0.027) and the size of the mass (P = 0.017) were significantly related to malign LNs. The patients' ages and sides of the masses were not significantly different between the malign and benign LN groups.


CONCLUSIONS
Lymph nodes constitute the majority of solitary SCF masses. Although imaging techniques and fine needle aspirations are routinely applied, excisional biopsies are necessary in most cases to reach an exact diagnosis and to plan a definitive treatment regime in this presented series.
