We report a case of Mycobacterium intracellulare (M. intracellulare) pulmonary infection with co-existing lung cancer and presenting as a solitary pulmonary nodule requiring differentiation from lung cancer. Computed tomography showed two nodules (20 mm) with spicula formation and pleural indentation on the right lower lobe of the lung (right S6 and S8). Transbronchial biopsies from the right S...
Acquired digital fibrokeratoma is an uncommon, benign fibrous tumor which usually occurs in adults as a solitary lesion. The most frequent locations are fingers and toes and the size of the tumor is generally small, around 3~5 mm. An 18-year-old female presented with a solitary, skin-colored, round and protruded nodule of the left great toe. The size of nodule was 2.5×1.6×1.4 cm. Histopathologi...
We describe the case of an 18-year-old female with Cowden syndrome in whom a simple x-ray detected a solitary pulmonary nodule that was identified as a sclerosing hemangioma. Pulmonary sclerosing hemangioma is an unusual lung neoplasm which typically presents as a solitary peripheral nodule in asymptomatic women. Although the histology of this entity is well defined, its origin and treatment is...
For a local field F with finite residue field, we count close vertices in the affine buildings of SLn(F ) and Spn(F ), addressing a question raised in [4]. In the case of SLn(F ), we give an explicit formula for the number ωn of vertices close to a given vertex. We establish the conjecture following Proposition 3.4 of [4] relating ωn and the number of chambers containing a given vertex. We give...
Quaternionic vector mKDV equations are derived from the Cartan structure equation in the symmetric space n =Sp(n+ 1)/Sp(1)×Sp(n). The derivation of the soliton hierarchy utilizes a moving parallel frame and a Cartan connection 1-form ω related to the Cartan geometry on n modelled on (spn+1, sp1 × spn). The integrability structure is shown to be geometrically encoded by a Poisson– Nijenhuis stru...
Background: Although thyroid nodules are less common in children and adolescents, the malignancy rate for nodules is higher among children and adolescents than adults. A nodule that is discovered in a patient presenting with hyperthyroidism is usually a benign nodule or benign toxic adenoma and, thus, nodules are biopsied only infrequently. Objective: To report a case of papillary thyroid carci...
To investigate the performance of combined 18F-FDG Positron Emission Tomography/Computed Tomography with high-resolution CT for differentiating invasive adenocarcinoma from adenocarcinoma in situ (pre-invasive lesion) or minimally invasive adenocarcinoma in stage IA lung cancer patients with solitary ground-glass opacity nodules. This retrospective study enrolled 58 consecutive stage IA pulmona...
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 79-year-old woman presented with a pulmonary nodule, which was incidentally found during regular health examination. Chest computed tomography revealed a solitary nodule of 1.4 cm in diameter located in the upper lobe of the right lung (A). Percutaneous ne...
For a local field F with finite residue field, we count close vertices in the affine buildings of SLn(F ) and Spn(F ), addressing a question of [4]. In the case of SLn(F ), we give an explicit formula for the number ωn of vertices close to a given vertex. We establish the conjecture following Proposition 3.4 of [4] relating ωn and the number of chambers containing a given vertex. We give analog...
For a local field K and n ≥ 2, let Ξn and ∆n denote the affine buildings naturally associated to the special linear and symplectic groups SLn(K) and Spn(K), respectively. We relate the number of vertices in Ξn (n ≥ 3) close (i.e., gallery distance 1) to a given vertex in Ξn to the number of chambers in Ξn containing the given vertex, proving a conjecture of Schwartz and Shemanske. We then consi...
