Summary
Human dirofilariasis, caused by Dirofilaria repens roundworms transmitted by mosquitoes, is increasing. This case highlights a painful temporal swelling diagnosed as cutaneous dirofilariasis.
Area of Science:
- Medical Parasitology
- Infectious Diseases
- Dermatology
Background:
- Dirofilariasis is a parasitic infection caused by Dirofilaria roundworms, primarily transmitted to humans through infected mosquito bites.
- Cutaneous dirofilariasis, often caused by Dirofilaria repens, manifests as subcutaneous parasitic nodules and is experiencing a rising incidence in human populations.
- Early diagnosis and prompt management are crucial for preventing complications associated with parasitic infections.
Observation:
- A 35-year-old woman presented with a three-week history of a painful swelling in the temporal region.
- Initial investigations revealed a roundworm within the subcutaneous fat and temporal muscle, with differential diagnoses including erysipelas, herpes zoster, and temporal arteritis.
- Ultrasound examination was instrumental in establishing the diagnosis of helminthiasis.
Findings:
- The case was diagnosed as cutaneous dirofilariasis caused by Dirofilaria repens.
- Microbiological examination of the surgically removed lesion confirmed the presence of a female Dirofilaria repens.
- Surgical excision was recommended and performed following multidisciplinary consultation.
Implications:
- This case underscores the importance of considering parasitic infections in the differential diagnosis of localized swellings, particularly in endemic areas.
- Increased awareness and diagnostic vigilance are necessary to manage the growing incidence of human dirofilariasis.
- Prompt surgical removal of the parasite is an effective treatment for cutaneous dirofilariasis, preventing further complications.

01:26Arteries of the Head and Neck
3.2K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:19Veins of Head and Neck
5.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:26Muscles of the Anterior Neck
4.8K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

01:03IR Frequency Region: Fingerprint Region
1.9K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

01:19Muscles that Move the Head
5.9K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
