Retromaxillary extension of PE air cells varies considerably and requires attention during ESS. Residual undissected retromaxillary cell is a common finding in revision ESS and can contribute to inadequate disease clearance.
There are many rheumatic diseases presenting with skin manifestations. This could be the first presenting feature of a systemic rheumatic disease. In addition, some of these skin manifestations could be an indication of an active disease or a sign of a serious medical emergency. In this chapter the skin manifestations of common rheumatic diseases will be described. Particular focus will be placed on rheumatic diseases with polyarthritis. The differential diagnosis of erythema nodosum will be discussed as this condition is observed in several disorders with arthritis. There are many drugs used in rheumatology. Some of them like allopurinol can lead to life-threatening dermatological conditions. A quick review on some of these conditions will be outlined. At the end of this chapter, the reader should be able to recognize different dermatological signs associated with patients with arthritis, discuss the differential diagnosis of erythema nodosum, and recognize life-threatening dermatological conditions.
Patient: Male, 23-year-old
Final Diagnosis: Squamous cell carcinoma
Symptoms: Right shoulder pain
Medication: —
Clinical Procedure: —
Specialty: Otolaryngology
Objective:
Rare coexistence of disease or pathology
Background:
Nasopharyngeal carcinoma (NPC) is a rare malignant tumor that arises from the mucosal lining epithelium of the nasopharynx, most commonly at the lateral nasopharyngeal recess or fossa of Rosenmüller. According to global age-standardized incidence rates (ASIRs), in 2018 the incidence rate of nasopharyngeal carcinoma varied from 2.1 to 0.4 per 100 000 in Asia and Europe, respectively. The number of deaths exceeded 50 000. It is one of the few head and neck tumors prone to distant metastasis, most commonly to bones, lung, and liver.
Case Report:
In this case report, we present a rare case in which a 23-year-old male patient presented to our head and neck clinic. The patient presented initially to the orthopedic clinic with a right humeral mass lesion 10 cm with history of pain for the last 7 months. A Tru-Cut biopsy confirmed metastatic NPC. A nasopharyngeal biopsy further revealed his lesion to be an NPC undifferentiated type III. The patient was diagnosed with a T

stage tumor and he was treated with chemoradiotherapy.
Conclusions:
NPCs that present with a shoulder/humoral metastasis are very rare clinically. We are presenting this case to increase the awareness of the Otolaryngology – Head & Neck surgery, Orthopedic, and Oncology community of such a rare presentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
