A familial case of Birt–Hogg–Dubé syndrome complicated with various cancers
Yuki Goto, Kazunori Tobino, Miyuki Munechika, Yuki Yoshimatsu, Hiromi Ide, Kosuke Tsuruno DOI: 10.1002/rcr2.549
Birt–Hogg–Dubé syndrome (BHDS) is a rare autosomal dominant inherited disorder characterized by fibrofolliculomas, renal tumours, lung cysts, and pneumothorax. This report described a familial case of BHDS complicated with various types of cancer (i.e. bladder, ureter, and lung). |
IgG4-related disease in the differential diagnosis of lung nodules
Hiroki Ishikawa, Hironori Uruga, Takeshi Fujii, Atsuko Kurosaki, Nasa Morokawa, Hisashi Takaya DOI: 10.1002/rcr2.550
We report a case of IgG4-related disease mimicking lung cancer with pleural dissemination. |
Eosinophilic granulomatous polyangiitis with IgG4 hypergammaglobulinaemia and salivary gland swelling
Koichiro Takahashi, Hironori Sadamatsu, Hiroki Tashiro, Go Kato, Masaru Uchida, Naoko Sueoka-Aragane DOI: 10.1002/rcr2.552
We present a case of a 51-year-old Japanese woman diagnosed with eosinophilic granulomatous polyangiitis (EGPA), a rare vasculitis that can occur in patients with eosinophilia and history of asthma, allergic rhinitis, and sinusitis, with immunoglobulin (Ig) G4 hypergammaglobulinaemia and salivary gland swelling. |
Peripheral pulmonary hamartoma with haemoptysis from the non-adjacent bronchus
Naoya Kitamura, Toshihiro Ojima DOI: 10.1002/rcr2.553
Here, we report a case involving a middle-aged man who developed a peripheral pulmonary hamartoma with haemoptysis from the non-adjacent bronchus and exhibited resolution of the haemoptysis after tumour enucleation. |
Oesophagobronchial perforations after placement of an oesophageal self-expanding metallic stent
Ken-ichi Tomiyama, Norimasa Ito, Kenichi Hayashi, Yuki Kawamoto, Hiroaki Shinoda, Nobuyuki Katakami DOI: 10.1002/rcr2.554
An oesophageal fully covered self-expanding metallic stent was inserted in a patient with advanced lung adenocarcinoma. After administration of pembrolizumab, he was hospitalized with septic shock caused by oesophagobronchial perforations. Owing to a drainage surgery and insertion of additional stents, he was recovered and pembrolizumab administration was re-initiated with complete resolution. |
Relapse of cervical tuberculous lymphadenitis immediately after completion of effective anti-tuberculosis treatments
Yuya Kimura, Masahiro Shimada, Masahiro Kawashima, Akira Yamane, Hideaki Nagai, Hirotoshi Matsui DOI: 10.1002/rcr2.555
Most cases of lymph node enlargement after completing tuberculosis (TB) treatment are due to paradoxical reaction (PR), not relapse, and therefore, do not require re-treatment. We herein report a case of a 28-year-old man who had developed cervical TB lymphadenitis and exhibited re-enlargement of the same lymph nodes one month after completing effective TB chemotherapy, which was microbiologically proven as relapse. |
Steroid resistance in organizing pneumonia caused by pulmonary cryptococcosis
Motoko Nomura, Hiromitsu Ohta, Masahiro Hiruta, Fumiaki Kudo, Fumiyoshi Ohyanagi, Yasuhiro Yamaguchi DOI: 10.1002/rcr2.556
Immunocompromised patients with pulmonary cryptococcosis show various computed tomography (CT) findings, and consolidation is frequently observed. Superimposed pulmonary cryptococcosis infection should be considered in cases of steroid-refractory cryptogenic organizing pneumonia (COP). |

Tegafur/gimeracil/oteracil-induced eosinophilic pneumonia
Toshiyuki Sumi, Hisashi Nakata, Yuji Mori, Hiroki Takahashi DOI: 10.1002/rcr2.551
We report a case of a 66-year-old man with drug-induced eosinophilic pneumonia secondary to tegafur/gimeracil/oteracil (TS-1) treatment for adenocarcinoma of the gastro-oesophageal junction. |
