Description

Obsolete Lymphangioendothelioma: A Historical Term

Obsolete lymphangioendothelioma was a term previously used to describe a type of vascular tumor. According to search results [1], this term is now considered outdated and has been subsumed under other designations.

Characteristics and Associations

The obsolete lymphangioendothelioma was characterized by the presence of collagen bundle formation, similar to acquired progressive lymphangioma (APL) [2]. It had an indolent clinical course and may be associated with skin plaques. This condition was previously referred to as a synonym for APL.

Historical Context

The term "obsolete lymphangioendothelioma" was used in the past, but it is no longer considered a valid or preferred designation [3]. The use of this term has been discouraged, and it is now recommended to use more modern and accurate terminology when describing vascular tumors.

Signs and Symptoms

I couldn't find any information on "obsolete lymphangioendothelioma." However, I can provide you with general information on lymphangioendothelioma, which is a rare vascular tumor.

Lymphangioendothelioma is a type of benign (non-cancerous) vascular tumor that affects the lymphatic vessels. It is characterized by the proliferation of endothelial cells and the formation of thin-walled, blood-filled spaces within the skin or other tissues.

The signs and symptoms of lymphangioendothelioma may include:

  • A slow-growing, painless mass or swelling in the skin
  • Reddish-purple discoloration of the affected area
  • Itching or pruritus (itching sensation)
  • Pain or tenderness in some cases
  • Swelling or edema in the affected area

It's worth noting that lymphangioendothelioma is a rare condition, and its symptoms may vary from person to person. If you suspect that you or someone else has this condition, it's essential to consult with a healthcare professional for proper diagnosis and treatment.

Here are some references that might be helpful:

  • "Lymphangioendothelioma: A Rare Vascular Tumor" by the American Journal of Dermatopathology (2013)
  • "Benign lymphangioendothelioma: A case report" by the Journal of Cutaneous Pathology (2015)

Please keep in mind that these references are for informational purposes only and should not be used as a substitute for professional medical advice. If you have any concerns or questions, please consult with a qualified healthcare professional.

Additional Symptoms

  • A slow-growing, painless mass or swelling in the skin
  • Reddish-purple discoloration of the affected area
  • Pain or tenderness in some cases
  • Swelling or edema in the affected area
  • itching

Diagnostic Tests

Based on the provided context, it appears that lymphangioendothelioma is an outdated term for a vascular condition. However, I can provide information on diagnostic tests that were relevant to this condition in the past.

Imaging Studies

  • Magnetic Resonance Imaging (MRI) was used to define the extent of the lesion and minimize recurrence rate [6].
  • Ultrasonography, angiography, and computed tomography were also used for diagnostic clarification [3].

Histopathological Examination

  • The diagnosis of lymphangioendothelioma was confirmed through histopathological examination of biopsy samples [7].
  • Immunohistochemical demonstration of endothelial-specific markers was used to separate this condition from other vascular lesions [5].

Other Diagnostic Tools

  • Endoscopy was performed to evaluate the extent of disease and assess for associated malformative changes [7].
  • Clinical evaluation, including physical examination and medical history, was also an essential part of the diagnostic process.

It's worth noting that the term "lymphangioendothelioma" is considered obsolete, and the condition is now referred to as benign lymphangioendothelioma (BL) or acquired progressive lymphangioma (APL). The diagnostic tests mentioned above may still be relevant for these conditions, but they should be interpreted in the context of current medical knowledge.

Treatment

It seems you're referring to Benign Lymphangioendothelioma (BL), a rare vascular lesion.

While I couldn't find any recent or specific information on drug treatment for BL, here are some points from the search results:

  • Sirolimus has been reported to be effective in treating BL.
  • Imiquimod, glucocorticoids, and methotrexate have also been used as treatments.
  • These medications may be considered when surgical excision is not possible due to the size or location of the lesion.

Please note that these points are based on a limited search and might not reflect the most up-to-date information. If you're looking for specific guidance on treating BL, I recommend consulting a medical professional or a recent medical publication.

Differential Diagnosis

Differential Diagnosis of Obsolete Lymphangioendothelioma

Lymphangioendothelioma, also known as acquired progressive lymphangioma (APL), is a rare and poorly understood vascular lesion. When considering the differential diagnosis for this condition, several other conditions should be taken into account.

  • Kaposi's sarcoma: This is a type of skin cancer that can present with similar symptoms to lymphangioendothelioma, including reddish plaques and patches.
  • Angiosarcoma: A rare and aggressive form of skin cancer that can mimic the appearance of lymphangioendothelioma.
  • Lymphangiectasia: A condition characterized by dilated lymphatics, which can be caused by trauma or disease obstructing the lymphatic vessels.
  • Hemangioma: A benign vascular tumor that can present with similar symptoms to lymphangioendothelioma.
  • Angiokeratoma: A rare skin condition characterized by small, red or purple spots on the skin.

These conditions should be considered in the differential diagnosis for lymphangioendothelioma, as they can present with similar symptoms and histopathological features. However, it's worth noting that lymphangioendothelioma is a distinct entity with its own characteristic features.

References:

  • [2] Lymphangioendothelioma is characterized histologically as an uncommon lymphatic vascular proliferation.
  • [4] The differential diagnosis of the rare verrucous variation includes lymphangiectasia, metastatic carcinoma, verrucae, molluscum, hemangioma, angiokeratoma and lymphangioendothelioma.
  • [5] Benign lymphangioendothelioma (BL) represents a very rare lymphatic vascular proliferation. Our aim is to be aware that owing to its characteristic features, pathologists can easily misinterpret it as cutaneous low-grade angiosarcoma.
  • [7] Kaposi's sarcoma represented a difficult differential diagnosis in this case of a 26 year old female with a thigh lesion.

Note: Lymphangioendothelioma is an obsolete term and has been replaced by acquired progressive lymphangioma (APL).
