Inflammatory myofibroblastoma (IMT) is a rare solid tumor, and its etiology and pathogenesis are unclear. Crohn's disease is a non-specific intestinal inflammatory disease. The clinical manifestations, laboratory examinations, and imaging examinations of IMT are not specific, making diagnosis difficult. A case of Crohn's disease combined with IMT of abdominal wall was admitted to the Department of Gastroenterology at the Third Xiangya Hospital, Central South University, on Nov. 21, 2017. This patient was admitted to our hospital because of repeated right lower abdominal pain for 4 years. A 6 cm×5 cm mass was palpated in the right lower abdomen. After completing the transanal double-balloon enteroscopy and computed tomographic enterography for the small intestinal, the cause was still unidentified. The patient underwent surgery due to an abdominal wall mass with intestinal fistula on Sept. 12, 2018 and recovered well currently. According to histopathology and immunohistochemistry, he was diagnosed with Crohn's disease combined with IMT. Up to July 2020, the patients still took azathioprine regularly, without abdominal pain, abdominal distension, and other discomfort, and the quality of his life was good.

OBJECTIVETo explore the causes, clinic diagnosis, treatment and prognosis of inflammatory myofibroblastic tumor (IMT) of the chest.

METHODSThe clinical data of 12 patients with IMT were retrospectively analyzed including 9 male and 3 female patients aged 36 to 81 years (mean 60.08 years). Five patients underwent pulmonary lobectomy and mediastinal lymph node dissection, 1 had partial lobectomy, 1 had mediastinal tumor resection and costectomy, and 2 received conservative treatment.

RESULTSAll the surgical patients recovered after surgery without lymph node metastasis detected by pathological examinations. In the follow-up lasting for 2 months to 5 years, no recurrence or metastasis occurred in these cases. In the 2 cases having conservative treatment, the tumor remained unchanged in one case at 3 month of follow-up and disappeared in the other case.

CONCLUSIONIMT in the chest is a rare benign tumor with a low incidence rate and malignancy. Pathological examination is reliable for definite diagnosis. Surgical operation is the primary therapeutic approach. All IMT patients should be closely followed up after the treatment.

Microcystic adnexal carcinoma (MAC) was first described in 1982 by Goldstein. Considered a rare malignant skin appendageal tumor, it is often underdiagnosed due to its clinical and histopathological resemblance to other cutaneous neoplasms. MAC is locally aggressive with infiltration of perineural spaces, subcutaneous tissue, skeletal muscles, and so on. Aggressive treatment including wide local excision, Mohs micrographic surgery, or radiation therapy is necessary owing to the high recurrence rate. Herein, we report a case of a 47-year-old Korean woman with a skin-colored hardened plaque on the scalp with a clinical diagnosis of cicatricial alopecia and histopathological diagnosis of MAC. After treatment by Mohs micrographic surgery, the patient is being followed up regularly without any sign of recurrence. This case demonstrates an uncommon topography of MAC on the scalp with secondary cicatricial alopecia and highlights the need for awareness of the potential for MAC in the diagnosis of alopecia with a slow-growing tumor.
