Thoracic lymphangitis as an immune-related adverse event: a case report.

The efficacy of immune checkpoint inhibitors (ICIs) has been widely recognized in several cancers and is now being used in the perioperative setting for lung cancer.We recently encountered an immune-related adverse event that has not been previously reported: thoracic lymphangitis, which occurred after postoperative ICI treatment for lung cancer. The patient complained of breathlessness and her condition rapidly progressed to hypoxia grade 3. Chest computed tomography revealed significant lymphostasis. With high-dose steroid treatment, the patient showed improvement.Therefore, as the frequency of neoadjuvant, adjuvant, and perioperative ICI use is expected to increase, it is crucial to understand and monitor this adverse event.

Lymphangitis From Scolopendra heros Envenomation: The Texas Redheaded Centipede.

Envenomation by Scolopendra heros, the Texas redheaded centipede, can present variably. Although transient pain and erythema are often treated conservatively, complications may include cellulitis, necrosis, myocardial infarction, and rhabdomyolysis. We present a case of an elderly man who came to the emergency department with lymphangitis and dermatitis secondary to a centipede sting that awoke him from sleep. It is important to recognize the potential of centipede envenomation to have severe local and systemic manifestations.

Lymphangitis occurring after intralesional Candida antigen injection for verruca vulgaris.

Verruca vulgaris is a common dermatological disease with many treatment options including destructive modalities and more recently, immunotherapy. Intralesional injections of Candida antigen have been described as a safe and effective treatment with the most common adverse reactions including local reactions (burning, blistering, peeling), local erythema, and pain at the injection site. We describe the first reported case of lymphangitis after intralesional Candida antigen injection for verruca vulgaris in a healthy 18-year-old woman. The lymphangitis rapidly resolved with ibuprofen and cold compresses. Physicians should be aware of this potential adverse reaction when using this treatment modality and should be familiar with appropriate treatment of subsequent lymphangitis.

Effect of lymphangiography on lymphedema.

Lymphangiography, using oily radiopaque Lipiodol Ultra Fluid has been shown to increase lymphedema in one-third of the patients with obstructive lymphedema and to cause lymphatic obliteration (demonstrated histologically). No effective element has been observed, although subclinical infection could not be ruled out. Allergy is another possible contributor, but the evidence from this series suggests that Lipiodol may act as a direct irritant when it is not rapidly cleared, as in the case of obstructive lymphedema, and proceed to obliteration of the residual lymphatics. On the basis of these findings, elective routine preoperative lymphangiography for lymphedema is considered strongly inadvisable.

Lymphangitis after tuberculin test.

After Mantoux testing with purified protein derivative (PPD) equivalent to 5 tuberculin units (TU), a 28 yr old man developed extensive erythema, induration and proximal lymphangitis. This is the only such case observed after Mantoux testing in approximately 500,000 subjects during 10 yrs in the Greek Army.

Pulmonary complications of methotrexate therapy.

Diffuse interstitial pulmonary infiltration was first reported in 1969, occurring during intermittent methotrexate therapy and it is suggested that it represents an adverse reaction to this drug. Despite the severity of the clinical and radiological changes, the disease is usually self-limiting. An additional case is presented and the previous 28 reported cases of this syndrome are summarized. Since intermittent methotrexate therapy is becoming more widely used, the importance of recognizing this respiratory illness as a possible complicating reaction to the drug is stressed.
